- Objects in free fall are subject only to
- the acceleration due to Earth's gravity g, which
- is defined as
-

- The acceleration is negative because gravity
- causes objects to accelerate toward the Earth.
- By convention, this direction is defined as the
- negative direction. Since the acceleration of
- gravity is constant, the equations for motion
- of objects with constant acceleration apply to
- objects in free fall.
