Difference between speen and velocity

Sl. No.

Differentiating Property

Velocity

Speed

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 change direction.

5

Change with time

• Velocity can decrease with time. For a moving object, it can be 0.

• Speed never decreases with time. For a moving object, it is never 0.

6

Interrelation

• An object may possess different velocities but the same speed.

• Speed may or may not be equal to velocity.

7

Unit (SI)

• Velocity is measured in m/s

• Speed is measured in m/s
