Question

a pendulum Bob is swinging with simple harmonic motion. its potential energy is maximum at? ​

Answer 1

At the two sides where the pendulum stops and change it's direction

Answer 2

At the highest 1 turning points of
oscillations, the kinetic energy
of the pendulum bob becomes zero
but as mechanical energy of the
pendulum is constant (that is due
to the conservative nature of gravitation
force) the potential energy
becomes maximum so the answer is at the turning points of oscillations
