A pendulum that is under motion exhibits massive amounts of energy. The important energies that are present in a swinging pendulum include both the kinetic and the potential energies (PE). These two forms of energies exist at the same time although in different quantities. Basically, what happens is that energy is transformed between the two forms of energy i.e. from potential energy to kinetic energy (KE) and vice versa. Importantly, â€œthe maximum PE occurs when the bob is momentarily at rest at its highest positionâ€ (Christiaan, 2007). On the other hand, the maximum KE is achieved when the bob is at the equilibrium position.
