Question

17. Why is the motion of a body moving with a constant speed around a circular path
said to be accelerated?
18. (i) Which of the following remains constant in uniform circular motion : Speed or
Velocity or both ?
(0) Name the force required for uniform circular motion. State its direction?​

Answer 1

here is your answer buddy...

1. If a body is in motion in a circular path it is said as the body is accelerated because its direction is changes at every point. The direction of velocity of the body is in the tangent to that point

2. As speed is scalar quantity. So, it has no direction but only has magnitude that's why we can say in uniform circular motion speed is constant but velocity is not because velocity has both magnitude and direction.

3. In uniform circular motion there is a centripetal force works. its its direction is towards the centre of the circular path.

hope this will help you a lot...!!!!
