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

15.(a)Uniform Motion : If a body travels equal distance in equal interval of time, no matters how small this interval may be, but in straight line is called uniform motion..

Non-Uniform motion: If a body travels unequal distance in equal interval of time, no matter how small this interval may be, but in circular path is called Non-uniform motion....

(b)Two example are :

i.an athlete running on a circular path in same distance and equal time.

ii.An clock run in same time and same distance .

(c)No,uniform circular motion is not a acceleration as in acceleration there is change in speed/velocity and also in time taken.In other hand in Uniform circular mtion there is no change in speed/velocity and also in time taken.☺❤♥
