Question

A stone tied to a thread is moved with a constant speed of 10 m/s along a circular park, but still its motion is said to be accelerated. Why?

Answer 1

Answer:

In a uniform circular motion, velocity of an object always increase at evert point of the circular path. Velocity is a vector qyantity and so dorection plays an important role in it. Speed has no relation with direction and so even if direction changes speed will be constant (if it is). Due to change in velocity we call it uniform accelerating motion

Answer 2

a stone is tied to A thread is no doubt moving with constant speed along a circular park but it is performing circular motion and as we know in circular motion speed remains constant but direction changes at every point direction is changing means velocity is changing and its velocity is changing then the motion is said to be accelerated motion
