Question

For a particle moving in vertical circle, the total energy at different positions along the path
A. is conserved
B. increases
C. decreases
D. may increases or decreases

Answer 1

Correct Answer - A
When a particle is moving a verticle circle it would move from lowest point to the highest point. Its speed would decreases and becomes minimum at the highest point. Thus, the total mechanical energy remains conserved, kinetic energy changes into potential energy and vice-versa.
