Question

give the name of the physical quantity that corresponds to the rate of change of velocity and write its SI unit

Answer 1

The velocity of a body is the rate of change of displacement with time .
It is a vector quantity.
Velocity= Displacement /time

Acceleration :
Acceleration is the rate of change of velocity with time.
Thus Acceleration=velocity/time
It is a vector quantity.

Answer 2

acceleration is the rate of change of velocity. its SI unit is m/s²
