Difference between Speed and Velocity

Differences between Speed and Velocity are the important topics in basic engineering. Here are the Key difference between Speed and Velocity you should know about.

Also, before reading the differences between these two, Let us know what is speed and velocity?

Define Speed

Speed can be defined as the rate of change of distance.

Define Velocity

Velocity is defined as the rate of change of displacement.

 

Speed Vs Velocity

Now, let us see the key difference between Speed and Velocity

        SPEED VELOCITY
It is defined as the rate of change of distance. Velocity is defined as the rate of change of displacement.
It is a scalar quantity. Velocity is a vector quantity.
It can never be negative or zero. It can be negative,zero or positive.
Speed is velocity without direction. Velocity is directed speed.
Speed may or may not be equal to velocity. A body may possess different velocities but the same speed.
Speed never decreases with time. For a moving body, it is never zero. Velocity can decrease with time. Also,For a moving body , it can be zero.
Speed in SI is measured in ms-1 Velocity in SI, is measured in ms-1
