Question

Difference between speed and velocity​

Answer 1

1 Definition

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.

2 Type of quantity

Vector quantity

Scalar quantity

3 Magnitude

Velocity can be zero, negative, or positive.

Speed can never be negative or zero.

4 Change of direction

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.

5 Interrelation

An object may possess different velocities but the same speed.

Speed may or may not be equal to velocity.

6 Unit (SI)

Velocity is measured in m/s

Speed is measured in m/s
