ReplyDeleteTo answer the questions from my understanding
ReplyDeleteDo objects naturally go in circles?- well I’d call it more of a oval but yes a circular motion. According to Kelplers first law all planets move about the sun in elliptical orbits, the sun being the focus point. This meaning it is always going around. Then again the shape isn’t quite a circle because as Kepler imagined it the sun would not be in the dead middle of the path. According to his second law the closer a planet goes to the sun the faster it goes and the farther the slower, this meaning the orbit does not look like a perfect circular motion, there is positive and negative acceleration. Plus in his third law it states the larger the planet the slower it goes, so there’s a number of things that don’t affect the path of the orbit but the way it looks. Still all orbits appear to be oval (circular). So technically the moon would orbit faster because it’s smaller and because it’s closer it’ll be faster at certain points in relative relation to the earth and suns orbit pattern. If the earth suddenly disappeared I think the moon would continue to orbit around another center but I’m not exactly sure. If the earth turned into a black mass or something unexplored then I guess the moon could just continue it’s orbit. These are just educated guesses but ah.
Consider if the earth were never there in the first place.
ReplyDeleteNo so much a before and after but a NEVER.
Consider this and site Newton’s first law while doing so.
Do objects naturally go in circles: yes, objects do tend to go in a circle/oval shape. We see half circles (parabolas) all the time when we throw things and they land back down. We also see it in space when gravity pulls all the planets in orbit around the sun in an oval shape.
ReplyDeleteWhat would happen if the Earth suddenly disappeared: I would guess that all the other planets would continue to orbit, but at a faster speed since there is now less mass pulling on gravity.
Do objects naturally go in circles? - Objects do naturally go in circles. Although they are not perfect circles, they do mimic a circular motion, or oval shape. Kepler's 1st law stated that the sun would be a little off center; therefore, the orbits of planets would not be perfect circles. If the Earth disappeared, I think the moon would start to orbit around something else. It would most likely fall out of the Earth's orbit, since it wouldn't be there. I think the moon is also related to the sun, so it would have that gravitational pull. If the Earth was NEVER there, I'm not exactly sure the moon would even be where it is now. The Giant Impactor Theory proposes a small planet hit Earth, creating matter to fall off, form the moon, and begin orbit. So, based on this theory, if the Earth was never here/there, I do not think there would be a moon.
ReplyDeleteDo objects naturally go in circles?: No, objects do not naturally go in circles, instead it will naturally go in a strait line. This is because of Newtons 1st law of motion. An object in motion will stay in motion unless acted on by an unbalanced force. So if an object was to move because of one force, and then have no other force act on it, it will go in a strait line, not a circle. When we throw an object and see it go in a parabola, it is because it falls towards the earth, but with no earth, it wouldn't have anything to curve towards. For an object to go in a circle, it must be constantly affected by another object, or for an example a moon being acted on by a planet. If that planet were to disappear, the moon would shoot out in a strait line tangent to it's orbital path because it wouldn't have the planet's gravity to orbit around. This will continue until it crashes into another object, or get's caught in the objects gravitational field and start to orbit the new object. When the moon orbits the earth normally, it's falling towards the earth, but also trying to move in a strait line tangent to the path it orbits at. Because of gravity, the moon doesn't go strait, but it unnaturally goes into a circle(more precisely and ellipse) around the planet. If the planet was never there in the first place, the moon would never orbit it or go in a circle/ellipse. So by the definition of naturally I'm using, as in an object being acted on by as little to no forces, it will naturally go in a strait line and not a circle.
ReplyDeleteDo objects naturally go in circles? - Yes, objects do naturally go in circles. They usually are not perfect circles, but they have a round/oval shape. Parabolas/Semi-circles are created due to gravity when an object is thrown, or when planets are pulled while in orbit. They also may not be perfect circles because the sun is not perfectly centered.
ReplyDeleteWhat would happen if earth disappeared? - I would predict that the planets may shift their path of orbit, but not greatly, and the moon would fall out of orbit due to it would most likely not be in existence if there was no earth in existence. The moons existence and purpose relies on planet earth. The moon also may continue to orbit due to Newtons first law.
Naturally, objects would not go in circles, but due to gravity they would. The gravitational pull of the sun causes all of the planets to orbit around it because it has a larger mass, therefore, more gravitational pull. This example also resembles how the moon orbits around the Earth; because the earth has a large mass, it has a large gravitational pull, causing the smaller moon to orbit around it. However, in a natural state, gravity would not exist, in fact, there would be no forces at all. In this case, planets would not orbit, and they would not accelerate. Newton’s first law states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an unbalanced force. This law supports the fact that an object in its natural state would not move, because the only way it would move is if a force was applied to it.
ReplyDeleteIf the earth never existed, not much would change. The other existing planets would still orbit around the sun. Compared to the current path these planets orbit however, and there would most likely be a slight change in the distance between them. For instance, Venus and Mars would be closer together because there is no planet orbiting in between them. Another point is that our moon probably wouldn’t exist without the earth, but if the earth went away and the moon was still there, the moon would probably continue moving in a straight line at its current velocity until it falls into another planet’s orbit. Newton’s first law would also support this theory.
Do objects naturally go in circles? - Objects do naturally go in a circular motion, but more of the shape of an oval. Newton realized that the sun's gravity pulls on the planets, forcing them to move in elliptical (circular) motions. In a circular orbit, the speed is constant, which also must mean the acceleration of gravity is also constant. This all relates back to an elliptical orbit and the gravity of the sun, which is what makes objects move in a circular motion.
ReplyDeleteWhat would happen if the earth disappeared? - If the earth disappeared, the solar system would act the same way. Since it is very small and doesn't have much mass compared to the other planets and the universe, it wouldn't have any major affect on anything.
Objects would naturally go in circles but not perfect ones. Objects will tend to fall into an oval shape but also close to a circle. For example, Kepler's First Law states that all planets move around the sun, making the sun the main point. But, the sun is not directly in the center so that would cause the planets not to orbit in a complete full circle. If the earth disappeared the moon would maybe start to orbit around something else because it has no more earth to orbit around itself with. But what if the earth was never there? In my opinion I believe that nothing would dramatically change and the planets will still be there being able to orbit around the sun.
ReplyDeleteObjects do go in circles naturally. Due to the gravitational pull planets, objects go in circles. Although they may be oval or many different shapes; semicircles or parabolas. However, depending upon what object it is, it’s orbit is different. Comparing the moon to an apple, the moon is larger causing it to orbit. The greater the mass, the more the gravitational pull. Issac Newton proves this theory with an equation involving the radius of the earth and it’s distance from the sun. However, in a natural state on earth, there is nothing for a simple object such as an apple to orbit around. Gravity plays a large role in the process. Referring back to the solar system, if there was no gravity there would be no forces. Netwon’s first law states “an object at rest will stay at rest and an object in motion will stay in motion unless an unbalanced force is applied to it”. This proves that objects do naturally go in circles because gravity is constant.
ReplyDeleteMeghan Kryjer’s response-
ReplyDeleteDo you objects Natalie go in circles? The answer to this question is yes objects to go in circles naturally (or oval like). CalPERS first law explains that the sun is the focus. And all the planets move around it in an elliptical orbit. In addition copper second law allows us to see that the plan is still for a bit in a perfect circle or motion. The farther away the planet is the son of the slower it goes but the closer the planet is the sun the faster it goes. Kelper’s first law explains that the sun is the focuspoint And all the planets move around it in an elliptical orbit. In addition Kelper’s second law allows us to see that the planets don’t orbit in a perfect circle or motion. The farther away the planet is the sun the slower it goes but the closer the planet is the sun the faster it goes.
What would happen if the earth disappeared? I assume that there would still be gravity in space allowing planets to keep orbiting. Although true I feel as though this be there to orbiting would increase. Like Kepler said the main point for planets orbiting is the sun since the earth is in front of other planets they orbit slower than if there wasn’t to be an earth. If there is no earth the other planets will be closer to the sun making them orbit faster.
Kelpers* hahahah
ReplyDeleteObjects DO NOT naturally go in circles. Because of Newton’s first law, and object in motion stays in motion.
ReplyDeleteIf the earth suddenly disappeared, the moon would do one of three things depending on where it is in it’s orbit around the earth: It might stay in orbit around the sun. It could go hurling towards the sun, or it could go flying towards the out skirts of the solar system, decelerate because of the sun’s gravity, and then go hurling towards the sun.
Do objects naturally go in circles?
ReplyDeleteIn a general circular motion, yes. I dont think it would necessarily be a perfect circle unless the objects focus was directly centered. Like the sun, all the planets that orbit the sun don't go in a perfect circle because it isn't in the direct center but they still orbit in a circular motion.
What would happen to the moon if there was no earth?
I believe the moon would start to circle around the sun like the rest of the planets. Since it is the next biggest/closest thing for the moon to focus on or orbit, but I do not think it would just fall out of orbit. Also I don't think the earth disappearing would have any effect on the rest of the solar system, being that the earth is quite small compared to the other planets.
Copernicus - professor of mathematics, doctor of medicine, a scholar of law, and was the forefront in modern astronomy. Created the "Revolution of heavenly Orbs" which consisted of the Copernican System based on Aristotle. He concluded that all objects did and still do move, naturally, in circles; to prove his theory, he used epicycles. Furthering his findings, he used epicycles and placed the sun in the very center and created numerous other circles which act as orbital paths of the planets. However, Kelper created his own set of laws which slightly varied from Copernicus'. Kelper, in his laws, he agreed with Copernicus to the point where the sun would be in inside the smallest epicycle, but he make ovals, and yet he moved the sun closer to one side, which proved his point where he found the planets move slower when far away from the sun and faster when closer to it.
ReplyDeleteSay the Earth were to suddenly disappear, I believe, based on Newton's laws and Kelper's ideas, the moon would travel through space in a straight line on the tangent of its orbital path when earth suddenly disappeared. The moon would keep going through space because there would be absolutely zero forces acting upon it. Once a gravitational force were applied, it could/would go back into orbit. For instance, it would be the same thing if I were to tie a ball on a string, then swing the string in a circle in the air, then suddenly let go; the ball would go flying in a straight line; just as the moon would if the Earth were to suddenly disappear.
do objects naturally go in circles— due to gravity and a certain amount of force objects would travel in a circular motion, but not in perfect circles. as stated in Kepler’s first law, earth and the other planets orbit around the sun in a circular motion. the sun is not in the direct center so the shape produced would look more like an oval. This is also similar to the moons orbit around the earth. The moon accelerates downward towards the earth due to the earths gravity. this causes it to move in a circular motion around the earth. the reason it moves in a circle is because it wants to move straight but is being pulled down.
ReplyDeletewhat would happen to the moon if the earth dissapeared—
if the earth dissapeared the moon would no longer move in a circular motion. the moon would now move at a constant velocity in a straight line. the moon would not be effected by the pull of gravity because it is not near any planets, but if it traveled close enough to another planet it could possibly start to orbit that planet. the other planets would be normal.
Do objects naturally go in circles- Objects do naturally move in circles, but more like an oval. Kelpers first law states that earth and other planets orbit around the sun in a circular motion. But since the sun is not isn't in the direct center they still orbit in a circular object.
ReplyDeleteWhat would the moon do if there was no Earth?- Since there is no Earth the moon would have no other planet near it to orbit around. It would not be possible for the moon to orbit another planet because of the long distance.
Do objects naturally move in circles?- Yes, objects do naturally move in circles due to the gravitational pull of the earth. Objects will also tend to move in oval shapes and in a parabola. If someone were to throw a ball up into the air, then that ball would follow a path of a parabola. The more mass an object has, the greater gravitational pull it has. If comparing a tennis ball to the moon, since the moon has more mass it creates a stronger gravitational pull and throws itself into orbit
ReplyDeleteIf the Earth were to suddenly disappear, then the moon's orbit would be thrown out of whack. If would travel at a constant velocity in a straight line until it was taken into another near by planet's gravitational pull. This would effect the overall gravitational pull of the new planet it has gone to and it would drastically throw off the tides, if there were any.
Do objects naturally move in circles? An object in orbit would naturally move in a circle, but an object not in orbit would not naturally move in a circle. It would naturally move in a straight line, because there is no force of gravity pulling it down. According to Newton’s first law, an object in motion stays in motion unless acted upon by another force. This proves that an object moving out of orbit will just keep going in a straight line since there is no gravity to pull it into a circular motion. An object in orbit is just constantly falling, because the object it is orbiting has gravity that pulls the orbiting object down towards its center continuously.
ReplyDeleteWhat would happen if to the moon if there was no earth? If the earth didn’t exist, the moon would have no force of gravity pulling it into orbit, therefore it would move at a constant velocity in a straight line because since there is no gravity, the net force would be zero. It would be comparable to the bowling ball in space we talked about in class. There is no net force, therefore there is no acceleration. That is, until it is acted upon by a force in space, maybe colliding with another object or becoming so close to another planet that it falls into orbit.
Do objects naturally go in circles? - Yes, objects do tend to form in a circular shape, but this form is more described as an oval. Due to the gravitational pull from the sun, it causes the surrounding plants to act in a circular motion. But since the sun is not directly is the middle, it causes the orbit to form a oval shape.
ReplyDeleteWhat would happen to the moon if the Earth Suddenly disappeared? - Since the moon orbits around the Earth, the moons orbit would have to change. This means the moon could move into a orbit closer or father from the sun. Also it may effect the orbit of the planet around it, since now it would be an unbalance orbit.
Do objects naturally go in circles? Objects in space do move in circles. If an object is in orbit, they will move in a circle. However, is an object is not in motion, it will not move in a circle. It would rather move in a straight line, because of gravity. This occurs in Earth.
ReplyDeleteIf the Earth suddenly disappeared, the moon would find another object to orbit around. Objects like comets or meteors find planets or the sun or orbit around. Since there is no gravity in space, tr moon would have to find something to orbit around in a circular motion.
Do objects naturally go in circles? Objects in space move in circles if they are far enough away from a planetoid with a strong enough gravitational pull to keep them in orbit. But, if they're close enough to the planetoid they will fall down to its' surface. When an object is on the ground, it will not move in a circle unless there is some sort of applied force because the gravity is pulling it to the planetoid, and the object is already on the surface.
ReplyDeleteIf the Earth suddenly disappeared, the moon could do two things:
1) It could keep going at the speed it was orbiting in the direction it was going forever
2) If it did the above but got close enough to an object of large mass, such as a nearby object like Jupiter or the sun, it could start orbiting one of those again.

(If my naturally you mean no other forces acting on it besides the initial force it took to get there)- Objects do not naturally move in circles, when they do move that way it means that gravity is moving them into orbit, which really only occurs in space. Objects naturally move in a straight line and would keep moving that way unless another force stops it, according to Newton's first law. But if something has enough mass in space gravity forces the objects to orbit around each other.
ReplyDeleteIf earth disappeared the moon would orbit around the sun.
I simply wanted to write down a quick word to say thanks to you for those wonderful tips and hints you are showing on this site.
