Question

11. (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

Answer:

a)uniform linear motion : motion with a constant velocity i.e direction as well as magnitude of speed doesn't change.

uniform circular motion: motion with a constant speed i.e magnitude remains same whereas the direction of motion keeps on changing ( moving in a circle).

b) examples of uniform circular motion:

1. wheel of a vehicle moving in a circular motion.

2.electrons moving around the nucleus.

3.a Merry go round in the full speed.

4.moving turbine, fans etc.

c) yes, uniform circular motion is an accelerated motion it has centripetal and centrifugal (tangential) acceleration.
