Question

Write an expression of speed for circular motion

Answer 1

Answer:

We know that speed=distance/time taken

So in the case of a circular path the distance will be the circumference i.e.

$2\pi \: r$

$so \\ speed = distance \div time \: \\ v = \frac{2\pi \: r}{t}$

Answer 2

Explanation:

as an object moves in a circle, it is constantly changing its direction .Accelerating objects are objects which are changing their velocity - either the speed(i.e. magnitude of the velocity vector) or the direction. An object understanding uniform circular motion is moving with a constant speed
