TYPES OF MOTION

TYPES OF MOTION

Motion can be classified into following three types.

• Translatory motion

• Rotatory motion

• Oscillatory (Vibratory) motion.

1. TRANSLATORY MOTION

Definition: A motion of a body in which every particle of the body is being displaced by the same amount is called translational motion.

EXAMPLES:

• Motion of a car on a straight road.

• Motion of a train.

• Motion of falling bodies.

2. ROTATORY MOTION

Definition: When an object spins or rotates about a fixed point or axis, its motion is called rotational motion. OR Motion confined to a circle is called rotatory motion.

EXAMPLES:

• Rotation of Ferris wheel.

• Rotation of wings of electric fan

• Rotation of electron around nucleus

3. OSCILLATORY (VIBRATORY) MOTION:

Definition: To and fro motion of an object about a mean position executed at regular intervals of time is called vibratory motion.

EXAMPLES:

• Motion of pendulum.

• To and fro motion of a swing.

• Motion of wings of a bird.
