Re: The affect of gravity

avogadro got it there.
execpt he is using gravatational feild strength to describe gravity.
Simple gravity on our earth is constant for all mass!!!
If u drop a bowling ball, and a tennis ball, from height of S, they will hit the ground at exactly the same time.

I saw something on Mythbusters once, don't remember that much tho

Re: The affect of gravity

"if one had the mass of the sun, that ball wouldn't actually fall

it would stay stationary and pull the earth towards it intill they collided"

thats why if you look at how i worded it, i didnt say fall, but "hit"

9.82ms^(-2) IIRC

Re: The affect of gravity

"the larger the mass of an object, the more gravity it exerts. if there were two balls with the same surface area and one was the mass of an orange and the other had the mass of our sun, if you dropped the one the mass of an orange first and then dropped the one the mass of the sun second, the one the mass of the sun would hit earth in less time"

Wrong smile

you can drop a marble and a bowling ball at the same height at the same time, and both would hit the floor at exactly the same time.  or milliseconds out due to the insignificant effect of the air resistance.  That all depends on the height in which you drop it.  but anything round will have less air resistance to something that is flat.

The same thing happens if you was to drop something from say a height of 10m and to throw something horizontal at a height of 10m, they both would hit the floor at the same time even though one of them is moving in a direction.

Why learn about something thats been and gone? when you can learn the future!

he is correct.

and skoe
it is
9.81ms^(-2)

Re: The affect of gravity

if you graph all the forces acting on ball, all the balls will have the same force pulling them down, but you're ignoring the gravity of the objects. this massive planet produces gravity so weak that we easily overpower it when we lift our limbs, and most objects we use have such small gravitational forces emiting from them that they dont make a measurable difference, a tiny scratch on the surface of one of the balls would probably make a larger difference. but if there was an extremely large mass, like one of another planet, in a ball the same size as another ball with a trivial amount of mass, they would collide faster then one with a trvial amount of mass.
