Video: What are speed and Velocity

Speed is the rate at which an object covers distance, while velocity is the rate at which an object covers distance in a specific direction.

The SI unit for speed is meters per second.

The average speed of an object is calculated by dividing the total distance traveled by the total time taken. The equation for average speed is: $average\ speed = \frac{total\ distance},{total\ time}$.
