Question

Difference between speed and velocity.​

Answer 1

Answer:-

Differentiation between speed and velocity.

Speed:-

•Speed is the rate of change of distance.

•It is a scalar quantity (which have either magnitude or direction). It have only direction.

•Speed may or may not be equal to velocity.

•Speed can be negative or 0.

•The SI unit of speed it ms-¹.

Velocity:-

•Velocity is the rate of change of displacement.

•It is a vector quantity (which have both magnitude and direction)

•A body may possess different velocity, but it has always the same speed.

•Velocity can be positive, negative or 0.

•The SI unit of velocity is ms-¹.

SPEED :--------

Distance covered by the particle in per unit time is known as speed.

Speed is a Scalar quantity and its usnit is m/s.

For a moving body speed is always positive it can never be negative.

For a moving body speed may be increasing or decreasing.

VELOCITY :------

Velocity of a body is the distance travelled by it per unit time in a given direction.

The SI unit of velocity is same as that of speed namely m/s.

Velocity is a vector Quantity..

It can be negative, positive or zero .
