Boru

Actually, if one considers the gravitational pull of the cannon ball and the bullet, the cannon ball must fall faster, albeit a negligible difference in that experiment.

Although not if you drop them next to each other, at the same time from the same height Smile

See, this is why I don't do physics. It's almost like meth ಠ_ಠ

What do you call the physics of meth?

Methaphysics.

I just realizdd that things fall upwards in Australia all the time!!! Omfg

It's plausible.
If a heavier object falls quicker,even slightly quicker than a lighter object,then it can't be a gravitational pull but a gravitational push. Dodgy Huh

I don't really understand how you came to the conclusion you came to.

A push is an action in which the body causing the pushing moves the object it is pushing away from it.
A pull is an action in which the body causing the pulling moves the object toward it.

Neither of those definitions has anything to do with acceleration, or with anything but the object causing the action and the object being acted on. That is, the comparison itself of how object A interacts with the earth to how object B interacts with the earth, tells us nothing about the nature of the force being applied to it. Only the description of the interaction between object A and the earth tells us the nature of the force being applied to object A from the Earth.

I'll tell you how i thought about this:


If you have two objects in front of you each attached to separate ropes and you pull each of the objects towards you the lighter object will come faster than the heavier object.
If you have two objects in front of you and if you had to push them away from you,you'd be able to push the lighter object away quicker than the heavier object.

If gravity was pulling stuff towards the center of earth then lighter objects would fall faster than heavier objects,but if it were pushing objects away from the surface of earth then heavier objects would fall faster than lighter object.

Get it?As in,get how i thought about it,not that i'm right or anything,it's just a thought.

Edit:
Like gravity would be like an imaginary bubble and when two objects were to be placed on top of it,the heavier object would come down faster than the lighter object,the bubble is pushing it up but it is overwhelmed.

Yeah, I get what you are saying more now. Still wrong, but I understand the thought process!

It seemed reasonable for me to be right to me,not to anyone else apparently. xD

Glad to help convey my moronic thoughts!

So why would objects fall at all in that picture? Tongue
