Zero Gravity

Zero gravity is when there is no gravity to influence an object, a state where there is no apparent acceleration due to gravity.

This doesn't mean there is no gravity, but when all the forces are added together the sum is zero.

A common zero gravity state occurs at the top of a roller coaster loop (nearly) and at the point "just as you stop before turning around" points on a swing at the playground.
