- acceleration due to gravity
- acceleration of an object that is subject only to the force of gravity; near Earth’s surface this acceleration is 9.80 m/s2
- average acceleration
- change in velocity divided by the time interval over which it changed
- constant acceleration
- acceleration that does not change with respect to time
- instantaneous acceleration
- rate of change of velocity at a specific instant in time
- kinematic equations
- the five equations that describe motion in terms of time, displacement, velocity, and acceleration
- negative acceleration
- acceleration in the negative direction
