Definition of acceleration: the ratio of the change of object speed to the corresponding time.

Physical meaning: a physical quantity indicating the speed of particle velocity change.

Unit: m/s 2 (m/s 2)

Acceleration a=(Vt-Vo)/t

With Vo as the positive direction, A and Vo are in the same direction (accelerating) a>0; On the other hand, a < 0

Initial velocity (Vo): m/s

Terminal speed: m/s

Time (t): seconds
