Answer- The above question is from the chapter 'Kinematics'.
Let's know about motion first.
Motion- It is the state when an object changes its position or location with time with respect to its surroundings.
Example: An oscillating pendulum, a person walking, etc. are examples of motion.
Rest and Motion are relative to each other.
This statement means that a person who is at rest may be in a motion with respect to other person or vice-versa.
Example: While travelling in bus, a person is at rest with respect to the other passengers. But the same person is in motion with respect to people outside.
