# Gravity

The theory of gravity describes how all things with mass are brought toward one another. Wolfram|Alpha incorporates this knowledge to compute the gravitational field of objects, the force of gravitation and the effects of gravity on motion.

Calculate the gravitational force, its effect on free falling objects and other mechanical effects of gravitation.
