- Acceleration is the rate of change of velocity and may be negative or positive.
- Average acceleration is expressed in m/s
^{2}and, in one dimension, can be calculated using $\overline{a}=\frac{\Delta v}{\Delta t}=\frac{{v}_{\text{f}}-{v}_{0}}{{t}_{\text{f}}-{t}_{o}}\text{.}$

- The kinematic equations show how time, displacement, velocity, and acceleration are related for objects in motion.
- In general, kinematic problems can be solved by identifying the kinematic equation that expresses the unknown in terms of the knowns.
- Displacement, velocity, and acceleration may be displayed graphically versus time.
