Question

How are we different?
(a) Oscillatory motion and linear motion.
(b) Linear motion and random motion.
(c) Random motion and oscillatory motion.

Answer 1

(a)

Oscillatory motion	Linear motion
The type of motion in which the object moves to and fro repeatedly about a mean or a fixed position is known as oscillatory motion.	The type of motion in which the object moves from one point to another in a straight line is called linear motion.
For example: Movement of the pendulum of a clock	For example: Vehicles moving on a straight road

(b)

Linear motion	Random motion
The type of motion in which the object moves from one point to another in a straight line is called linear motion.	The type of motion in which the direction of motion and the speed of an object changes continuously is called random motion.
For example: Vehicles moving on a straight road	For example: Children playing in a garden

(c)

Random motion	Oscillatory motion
The type of motion in which the direction of motion and the speed of an object changes continuously is called random motion.	The type of motion in which the object moves to and fro repeatedly about a mean or a fixed position is known as oscillatory motion.
For example: Children playing in a garden	For example: Movement of the pendulum of a clock
