if we take newton's example of the falling apple,?

Question

the apple should attract the earth as much the earth attracts the apple.so why does'nt the earth go up to meet the apple instead of the apple falling to meet the earth?

Answer 1

I'm guessing because the earth contains a centre of gravity and the apple doesn't.

Answer 2

Bcoz the earth has the gravitational field which the apple hasn't. So normally the earth should attract the apple not the apple attract the earth. Here the gravitational field means inside our earth which is call the centre of earth has a magnatic field which is able to attract any kind of things.In science it is denoted by (g).
If u r a higher class student u lookafter the physics book of class-XII.

Answer 3

Well, the Earth is already moving slowly towards the Sun, and always has been, only it's really too slow a movement for anyone to bother about it much. However, there are plenty of planets without moons, and they manage to keep a constant orbit, so I don't think that we would. If the major theories are correct, then we were already orbiting the Sun for millions of years before the moon started orbiting Earth, so removing the moon would have little effect on our orbit.

Answer 4

It does, but remember that if you are trying to measure it experimentally, then first of all YOU and your apparatus will most likely be on Earth and YOU and your apparatus will move WITH THE EARTH and you won't "see" it so to speak.

Second, if you somehow you were able to overcome this problem, the difference will be sooooooooooooooooooooooooooooooo small that so far it is only mathematically possible to calculate it. We do not have instruments that are good enough to measure such small changes.

The mass of the apple compared to the mass of our planet is a bit smaller.

Answer 5

the earth is infinitely heavier than the apple ma'am!!!

and earth's gravitational pull attracts the apple, just as sun's gravitational pull attracts the earth, thats wby the earth revolves around the sun and not vice - versa.

Answer 6

yes, apple also attact earth .. but the attraction force is so small that it produces accelation equal to zero on to earth ...

anyways .. apple has center of gravity located at center of apple .
Center of gravity is that point on to the object or may lay outside where we may consider the whole mass of the body to be located (this assumpsion is done for mathematial calculation)

Answer 7

You are making a wrong assumption about gravity.Gravity increases with mass.The moon is much smaller than the earth and its gravity is 1/6th that of earth.The apples gravity is barely perceptible.

Answer 8

i think b'coz the wt of earth is more than that of apple & apple does'nt have centre of gravity

Answer 9

apple fall down to earth coz earth has gravitational force. earth attracts every object in its gravitational area. apple doesn't hav any such force so every apple fall down to earth wen its detached from its tree.

Answer 10

i'm guessing because the earth contains a centre of gravity and the apple doesn't.
