Question

Prove that motion in vertical circle is an example of non uniform circular motion.

Answer 1

Answer:

because circle is circlura in Nate

Answer 2

Answer:

Because the direction of force  is different at different points of the circle gravity is always changing either speeding up or slowing down.

Explanation:

using centripetal formula we will see that at the top net result will be different form result  at the bottom with sign.

for uniform motion.

Net force should be same and towards the center of the circle.

at the top of the circle here net force = T+ mg

so ( MV^2)/r= T+mg

Tension = (MV^2)/r + mg

at the bottom

F= T-mg ( because both are in opposite direction )

T= (MV^2)/r - mg

but in uniform circle Tension is always uniform but here its with opposite direction .

also when the body is moving downward it will fall freely and speed up and when body is moving in upward direction speed will be reduced down to zero at the top of the circle
