A mass m is attached to a string of length r and is swung in a vertical circle. The mass is released from the top of the circle. The study focuses on the forces acting on the mass and the concepts of centripetal force, tension, and energy transformations.
Assertion (A): The total mechanical energy of a simple harmonic oscillator remains constant during oscillation. Reason (R): Energy is continuously converted between kinetic and potential forms, but the total energy remains unchanged.
