Q:
# What is the equation for velocity?

**The equation for velocity is displacement divided by time.** The equations for speed and velocity are similar, but velocity must always have direction, whereas speed does not.

While speed is a measure of how fast something is moving, velocity is a measure of the rate an object changes its position. Distance is a measure of how far something is, while displacement is a measure of the shortest distance between an object's start point and its end point. For example, a runner who ran 400 meters around a track travelled a distance of 400 meters. However, he has a displacement of 0 because he ended up at the same place he started.
