Question

why work done in circular motion is zero? ​

Answer 1

I HOPE THIS WILL HELP YOU ^_^

Answer 2

1.because displacement is 0

(displacement is difference between final and initial position)

2. as abt cos theeta its also 0

ref the image, the angle betw direction of force and displacement is 90°

cos 90= 0

and we know,

work= force*displacement*cos theeta

hope it helps

good day
