Question

distinguish between speed and velocity

Answer 1

SPEED:

Speed is defined as the rate of change of distance with respect to time.

Speed is a scalar quantity that means speed does not require direction,it just has magnitude.

S.I unit of speed is m/s.

Speed is greater or equal to velocity but can't be less than velocity.

VELOCITY:

Velocity is defined as the rate of change of displacement with respect to time.

Velocity is a vector quantity that means with magnitude it requires direction.

S.I.unit of velocity is same as that of speed that is m/s.

Velocity can be zero,equal to speed but can't be greater than speed.

Answer 2

speed is the total distance taken in unit time.si unit is m/s. velocity is the speed of an object moving in a definite direction. si unit is m/s
