Velocity shows how fast an object is moving to which direction. Average velocity can be calculated by dividing displacement over time.


For example, when a car moved 50 km in 2 hours, the average velocity is 25.5 km/h because .

The instantaneous velocity shows the velocity of an object at one point. For example, when you are driving a car and its speedometer swings to 90 km/h, then the instantaneous velocity of the car is 90 km/h.
