Types of Motion

Q. How many types of motion of a body do you know? Describe each type briefly?

Types of Motion

Three types of motion can be produced in a body.

In this type of motion every particle of the body is displaced by the same amount.

Example

(1) Moving car on a road.

(2) A train on its track.

(3) Bodies falling on the ground.

(b) Rotational Motion

When an object spins or rotates about a fixed point or axis, its motion is called rotational motion.

Example:

(1) The rotation of earth about its own axis.

(2) Rotating wheel of stationary cycle.

(3) Blades of moving electric fan.

(c) Oscillatory motion
