Question

Distinguish between speed and velocity.

Answer 1

Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. Speed is ignorant of direction. On the other hand, velocity is a vector quantity; it is direction-aware.

Answer 2

1. Speed is distance covered per unit time while velocity is displacement per unit time. 2. Speed is scalar while velocity is vector physical quantity.
