Question

15. (a) Differentiate between uniform linear and uniform circular motion.
(b) Write any four examples of uniform circular motion
(c) Is uniform circular motion accelerated motion?​

Answer 1

(a)ANSWER

The basic difference between uniform linear motion & uniform circular motion is.

Uniform Linear Motion:

Velocity is constant & thus it is a uniform motion. Acceleration is zero.

Uniform Circular Motion:

Velocity is not constant due to continuous change in Direction & thus it is not a uniform motion.

(b) ANSWER

Examples of circular motion include: an artificial satellite orbiting the Earth at a constant height, a ceiling fan's blades rotating around a hub, a stone which is tied to a rope and is being swung in circles, a car turning through a curve in a race track, an electron moving perpendicular to a uniform magnetic field, ...

Answer 2

Explanation:

a)Uniform linear Motion

1. An object moves in a circular motion with equal interval of time.

Uniform circular motion

1. An object moves along with the circumference of a circle.

b) Examples

1. Rotation of a clock.
2. Rotation of a wheel.

c) Yes Uniform circular motion is an accelerated motion
