Question

What energy changes take place in an oscillating pendulum?

Answer 1

At A P.E. is max and K.E. is zero 

As bob moves towards B, P.E. goes on decreasing K.E. goes on increasing 

P.E. = zero K.E.max 

As the bob moves to C 

K.E. goes on decreasing and P.E. goes on increasing

AtC 

P.E. is maximum and K.E. is zero
