Question

define state of rest and state of motion and what are the types of motion.

Answer 1

Rest (physics) ... According to the theory of relativity, it is said that an object is "at rest relative to" another. Two or more than two objects are said to be at rest, if its position with respect to each other is not changing or moving with uniform velocity with respect to each other; rest andmotion are relative term.

Answer 2

rest is the state of an object being stationary relative to a particular frame of reference or another object; when the position of a body with respect to its surroundings does not change with time it is said to be "at rest".
Types of motion

Simple harmonic motion – (e.g., that of a pendulum).

Linear motion – motion which follows a straight linear path, and whose displacement is exactly the same as its trajectory.

Reciprocal motion (e.g. vibration)

Random motion (e.g. vibration)

Brownian motion (i.e. the random movement of particles)

etc
