Difference Between Speed and Velocity

Velocity

Speed

Velocity can be defined as the rate at which an object changes position in a certain direction

The rate at which an object covers a certain distance is known as speed

The velocity of the object changes with the change in direction, therefore the object must follow one direction

The average speed will continue to count even if the object changes direction

Vector quantity

Scalar quantity

Velocity can be zero, negative, or positive

Speed can never be negative or zero
