Explain translatory motion and give examples of various types of translatory motion.

Difficulty: Medium

Translatory motion:

In translation motion, a body moves along a line without any rotation. The line may be straight or curved.

Examples:

Riders moving on the Ferris wheel are also in translational motion. Their motion is in a circle without rotation.

Types of Translatory motion:

Translatory motion can be divided into linear motion, circular motion, and random motion.

1. Linear motion:

The straight-line motion of a body is called linear motion.

Examples:

The motion of objects such as a car moving on a straight and level road is linear motion.

Airplanes flying straight in the air and objects falling vertically down are also examples of linear motion.

2. Circular motion:

The motion of an object in a circular path is called circular motion.

Examples:

A stone tied at the end of a string can be made to whirl. The stone moves in a circle and thus has a circular motion.

Toy train moving on a circular track. A bicycle or a car moving along a circular track possess circular motion.

The motion of the earth around the sun and the motion of the moon around the earth are also examples of circular motion.

3. Random Motion:

The disordered or irregular motion of an object is called random motion.

Examples:

The motion of insects and birds is irregular. Thus, the motion of insects and birds is random

The motion of dust or smoke particles in the air is also random.

The Brownian motion of a gas or liquid molecules along a zigzag path as shown in the figure is also an example of random motion.
