The Equations of Constant Acceleration
Acceleration is a measure of how rapidly an object speeds up or slows down, or more specifically, how much its velocity changes over some given interval of time. Acceleration can be measured both at a point in time, the result being called instantaneous acceleration, or over some finite time interval, called an average acceleration. Constant acceleration exists whenever both measures of acceleration remain the same for some period of time. During these time periods, average acceleration, , and instantaneous acceleration, a, are equal, and both hold at one value regardless of the length ...
