Question

distinction between speed and velocity

Answer 1

velocity
it is a vector quantity
average velocity can be zero
the rate of change of displacement
speed
it is scalar quantity
average speed cannot be zero
the rate of change of distance

Answer 2

Velocity: Velocity is a vector quantity which means it has both magnitude and direction. It denotes the rate at which the object is moving or changing position.

Velocity=dispacement/time

Speed: Speed is a scalar quantity which means it has no direction. It denotes how fast an object is moving.

Speed=distance /time
