Velocity is one of the most important concepts in physics. It describes how fast an object moves and in which direction.
Velocity is defined as the rate of change of displacement with time.
The formula for velocity is:
Velocity = Displacement ÷ Time
Example
A car travels 60 meters in 10 seconds.
Velocity = 60 ÷ 10
Velocity = 6 meters per second
This means the car moves 6 meters every second.
Velocity vs Speed
Speed only tells us how fast something moves.
Velocity tells us how fast and in which direction.
For example:
60 km/h east is velocity because direction is included.
Quick Tip
Velocity always includes both magnitude and direction.
