Question

what is the rate of change of displacement, momentum, velocity and give some examples of rate of change in some physical quantities ?

Answer 1

rate of change of displacement = velocity velocity =v-u/t

Answer 2

Hey mate here is your answer!

DISPLACEMENT:-A displacement is a vector whose length is the shortest distance from the initial to the final position of a point P.

MOMENTUM:- simply momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction in three-dimensional space.

VELOCITY:-The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. 

Some examples of physical quantities are as follows :-
1. length
2. mass
3. time
4. electric current
