Question

suppose a boy is enjoying a ride on merry go round which is moving with constant speed of 10m/s? what is motion of boy?

Answer 1

In a merry go round,the speed is constant but the velocity is not constant because its direction will be changing i.e, there is acceleration in the motion.So the boy is in accelerated motion.

Answer 2

Given boy is enjoying a ride on merry go round which is moving with constant speed of 10m/s.
So, when the boy moves in a circular path ( merry go round) with uniform speed it's motion is uniform circular motion.
In uniform circular motion, speed remains contant, but the direction of motion is constantly changing.
Motion of an object in a circle with constant speed is an example of accelerated motion.
