Their tangential velocity allows them to remain in orbital motion while the force of gravity pulls them inward. Many students believe that orbiting astronauts are weightless because they do not experience a force of gravity.

The acceleration gained by an object because of gravitational force is called its acceleration due to gravity. Its SI unit is m/s2 . ... The acceleration due to gravity at the surface of Earth is represented as g. It has a standard value defined as 9.80665 m/s2.

is a form of motion in which an object or particle (called a projectile) is thrown near the earth's surface, and it moves along a curved path under the action of gravity only. The implication here is that air resistance is negligible, or in any case is being neglected in all of these equations.

the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration.
