A student is demonstrating the transformation of kinetic and potential energy in a system using the pendulum shown below.At which point in this system does the pendulum bob demonstrate minimum potential energy?
In the pendulum system, the potential energy is at a minimum when the pendulum bob reaches its highest point, or the maximum displacement from its equilibrium position. This is because at this point, the bob has gained maximum kinetic energy as it is at its maximum velocity, and all the potential energy has been converted into kinetic energy. Conversely, when the pendulum bob is at its lowest point or the equilibrium position, it has maximum potential energy and minimum kinetic energy. Therefore, the point at which the pendulum bob demonstrates minimum potential energy is at its highest point in the system.
