The different types of motion are explained with examples as given below:
1. Translational motion
A motion in which all parts of an object move equal distance in a given time is called translational motion.
Types of translational motion:
(i) Rectilinear motion
(ii) Curvilinear motion
When an object in translational motion moves in a straight line, it is said to be in rectilinear motion.
Example: Motion of a car on a straight road.
When an object in translational motion moves along a curved path, it is said to be in curvilinear motion.
Example: Motion of a car taking a turn.
2. Rotational motion
When an object moves about an axis and different parts of it move by unequal distances in a given interval of time, it is said to be in rotational motion.
Example: Motion of blades of a windmill.
3. Periodic motion
A motion that repeats itself after equal intervals of time is called periodic motion.
Example: The to and fro motion of a pendulum.
4. Non-periodic motion
A motion that does not repeat itself at regular intervals of time is called non-periodic motion.
Example: Birds gliding across the sky.
