For a simple pendulum, a graph is plotted between its kinetic energy (KE) and potential energy (PE) against its displacement d. Which one of the following represents these correctly?
A simple pendulum performs simple harmonic motion.
For simple harmonic motion.
Potential energy foes as 12m ω2x2
The maximum potential energy being 12m ω2A2
Kinetic energy does as 12mω2(A2−x2). Graph (b) fits these plots.
