Rate of change of displacement is called velocity

(i) Velocity is defined as the rate of change of displacement.

(ii) $\boxed{\bold{\sf{Velocity =\dfrac{Change\:in\:displacement}{Time}}}}$

(iii) Velocity is a vector quantity, ie it has magnitude as well as direction.

(iv) The SI unit of velocity is m/s

(v) The dimension of velocity is [L]

(vi) The values of velocity can be positive, negative and zero.

(i) It is defined as the rate of change of distance.

(ii) $\boxed{\bold{\sf{Speed =\dfrac{Change\:in\:distance}{Time}}}}$

(iii) speed is a scalar quantity ie it has magnitude but no direction.

(iv) The SI unit of speed is m/s

(v) The dimension of speed is [L]

(vi) The value for Speed can be positive and zero but not negative.
