Question

GIVE TWO EXAMPLES OF UNIFORM AND NON-UNIFORM MOTION

Answer 1

Definition: Uniform motion is defined as the motion of an object in which the object travels in a straight line and its velocity remains constant along that line as it covers equal distances in equal intervals of time, irrespective of the length of the time.

Uniform Motion

If a body is involved in rectilinear motion and the motion is uniform, then the acceleration of the body must be zero.

Example:

If the speed of a car is 10 m/s, it means that the car covers 10 meters in one second. The speed is constant in every second.
Movement of blades of a ceiling fan.
Non Uniform Motion:

Definition: Non Uniform motion is defined as the motion of an object in which the object travels with varied speed and it does not cover same distance in equal time intervals, irrespective of the time interval length.

Non Uniform Motion

If a body is involved in rectilinear motion, and if the motion is non-uniform, then the acceleration of the body must be non-zero.

Example:

If a car covers 10 meters in first two seconds, and 15 meters in next two seconds.
The motion of a train.

Answer 2

Answer:

Uniform Motion:

The Motion of earth around the sun.

The Motion of a sling that is rotated by ones hands.

Non uniform Motion:

A car moving on a crowded street.

A person jogging in a park.
