Explain the difference between speed and velocity.

Speed is the rate of change in direction, whereas velocity is the rate of change in displacement. This means that an object's velocity has an associated direction whereas its speed doesn't.If a car travells around a roundabout, its speed may always be 20mph, but its velocity will be constantly changing as it is constantly changing direction.
