1. Mechanical Energy: This is the energy of motion. Our bodies use chemical energy from food to power muscles, allowing us to walk, run, lift objects, and perform all sorts of physical activities.
2. Thermal Energy (Heat): Our bodies generate heat as a byproduct of metabolism, which is the process of breaking down food to release energy. This heat helps maintain our body temperature.
3. Electrical Energy: Our nervous system relies on electrical signals to transmit information throughout the body. These signals are generated by the movement of ions across cell membranes, a process that is powered by chemical energy from food.
