Infinity Learn · Accepted Answer

Motion is the change in position of an object with respect to time. There are three types of motion. They are:

a) Straight line motion - It is a type of motion in which the object moves from one point to another in a straight line.

For example: Vehicles moving on a straight road

b) Oscillatory motion - It is a type of motion in which the object moves to and fro repeatedly about a mean or a fixed position.

For example: Movement of the pendulum of a clock

c) Circular motion - It is a type of motion in which the object moves along a circular path.
