Definition: The effect of the curvature of space time in Einstein’s General Theory of Relativity on the paths of moving objects. In most cases, gravity can be approximated as a force attracting massive bodies towards each other that is proportional to the product of their masses and inversely proportional to the square of their separation.

Near the surface of the earth, the effect of gravity is a constant downwards force on every object that, if unopposed, would yield an acceleration 9.8 m/s/s

Also Known As: weight

Examples: ones weight, as opposed to ones mass, is a measure of the gravitational force a body experiences.
