That Galileo discovered.
I have a project on him due Monday, and I don't understand the definitions I've found.
Thanks. :)

Contrary to the view held by Aristotle, Galileo demonstrated that " the time of descent of falling bodies is independent of their mass". Applying this principle, he also conducted further experiments to derive a formula for accelaration and proved that " distance of descent is proportional to the square of time of descent. d > t^2 (I used > sign here to mean 'proportional to')

The distance a body has fallen at any instant is proportional to the square of the time spent falling.
So we can conclude:
The distance all bodies fall in a vacuum is proportional to the square of the time.
The speed of all falling bodies in a vacuum is proportional to time.
Use the following algebraic expressions to solve problems describing the motion of bodies in free fall
(a) s = 1/2gt^2, (b) v = gt, (c) a = g.

In the absence of "accidental" influences such as air resistance, All bodies fall to Earth at the same rate, regardless of their mass.

When bodies fall, it hurts. Sometime when they fall hard enough, they don't get up.
