(a) Displacement;
(b) Velocity;
(c) Acceleration.

Answer 1

(a) Displacement :- a displacement is a vector quantity whose length is shortage distance between initial and final position .

(b) velocity :- the rate at which displacement covered is called velocity .

(c) Acceleration :- the rate of change of velocity is called acceleration .

Answer 2

Here is your answer mate..

1. Displacement : The shortest distance between the initial and final position of a body is called displacement.

2. Velocity : The distance covered by the body in a specified direction is called velocity.
Velocity is a vector quantity. It's S.I unit is m/s.

3.Acceleration : The rate of change of velocity in per unit time is called Acceleration. It is vector quantity. It's S.I unit is m/s^2
