... In the last example the force on each planet is the same. This is due to to Newton’s third law of motion: the force on Planet 1 due to Planet 2 is just as strong but in the opposite direction as the force on Planet 2 due to Planet 1. The effects of these forces are not the same, however, since the p ...

... • Gravity is the force of attraction between two objects. • The strength of gravity depends on an object’s mass and distance. • For example, the moon’s gravity is 1/6 of the Earth’s gravity because it is much smaller. • Where would gravity be less, at sea level or on top of a mountain? ...
