Question

An object is moving with uniform speed in a circle of radius r. Calculate the distance
and displacement. (a) When it completes half the circle (b) When it completes full circle. (c) What type of motion does the object passess?(Justify your answer)​

Answer 1

Answer:

Explanation:The object is moving with uniform speed means it covers equal distance in equal time.

 Now, as we know here, object is moving in circular path with uniform speed. So, distance and displacement are respectively:-

a] When completes half circle-

     Distance - πr, Displacement - 2r

b]When completes full circle-

    Distance- equal to perimeter; that is 2πr,  Displacement- Zero; as the object reached the same point from where it started.

c]The object is moving in uniform circular motion or we can also define it as periodic motion in circular path.

HOPE you got your answer.
