GRAVITY - LAB

OBJECTIVE:
Determine the importance of gravity and how it affects us.

BACKGROUND:
The universal law of gravitation states that every object in the universe is attracted to every other objects in the universe.  Everything pulls on everything else, and in a beautifully simple  way that involves only mass and distance.  Newton stated that every body attracts every other body with a force which for any two bodies in proportion to the mass of each body and which decreases proportionately to the mass of each body and which decreases proportionately as the square of the distance between them.
