Answer:
rolling wheel.
Step-by-step explanation:
Mechanical energy refers to the energy possessed by an object due to its motion or position. It can be further divided into kinetic energy and potential energy.
In the case of a rolling wheel, it exhibits both types of mechanical energy. When the wheel is in motion, it possesses kinetic energy. The faster it rolls, the greater its kinetic energy. This energy is associated with the motion of the wheel.
Additionally, the rolling wheel can also possess potential energy. This occurs when the wheel is elevated or positioned higher than the ground level. The higher the position, the greater the potential energy. When the wheel is allowed to roll downhill, for example, the potential energy is converted into kinetic energy, causing the wheel to accelerate.
Hence, a rolling wheel serves as an example of mechanical energy as it exhibits both kinetic energy and potential energy.
