... In keeping with Aristotelian notions, Kepler believed that a force was necessary to drive the planets along their orbits, not to keep them in orbit. Consequently, Kepler was unable to provide a correct explanation for these three laws. It was not until Newton that the single unifying reason for thes ...

... He explained Galileo’s experiment this way: Objects have what he called inertial mass, their resistance to being accelerated. A more massive object is harder to “get moving” (accelerate) than a less massive one. But, he reasoned, if the more massive object is falling at the same rate as the less mas ...

Other astronomical bodies, particularly the sun and the moon, exert a very small gravitational force on objects at the earth's surface, depending on their relative positions. This causes the net gravitational force to vary by a small amount, and ...
