Acceleration is the rate of change of velocity and may be negative or positive.
Average acceleration is expressed in m/s² and, in one dimension, can be calculated using $\bar{a} = \frac{Δ v}{Δ t} = \frac{v_{f} - v_{0}}{t_{f} - t_{o}} .$

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.
