(a) Circular motion - (iii) revolution of earth around the sun Circular motion is a special type of curvilinear motion. The revolution of earth around the sun is an example of circular motion. (b) periodic motion - (v) motion of pendulum of a clock A motion which gets repeated after a regular interval of time is called a periodic motion. The motion of pendulum of a clock is periodic motion. (c) Vibratory motion - (iv) motion of wire of a guitar A type of motion in which a particle moves to and fro about a fixed point is known as vibratory motion. The motion of wire of a guitar is vibratory motion. Vibrations are also called quick oscillations . (d) Rotatory motion - (i) a running fan In rotatory motion, different parts of the object move through different distances during the same time. A running fan executes rotatory motion. (e) Non uniform motion - (ii) a car moving in a market If a moving body travels unequal distances in equal intervals of time in a fixed direction, its motion is said to be non-uniform motion. For example a car moving in a market executes non uniform motion.
