Which type of energy is highest at the maximum height of a pendulum swing?

At the maximum height of a pendulum swing, the pendulum reaches its highest point in terms of vertical displacement from the lowest point of the swing. At this position, the kinetic energy of the pendulum is at its minimum because the speed of the pendulum is zero—this is when it momentarily stops before reversing direction.

Conversely, potential energy, which depends on the height of an object relative to a reference point (typically the lowest point in the swing), is at its maximum at this height. The potential energy is calculated using the formula (PE = mgh), where (m) is the mass, (g) is the acceleration due to gravity, and (h) is the height above the reference point. Therefore, since the pendulum is at its highest position, this energy is maximized at that point.

Thermal energy and electrical energy are not relevant in this context as they do not directly correlate to the pendulum's movement or energy transformation during its swing. Thus, potential energy being highest at the maximum height aligns with the principles of energy conservation in a pendulum system.
