Answer:
When your body moves it uses muscles, which contract and convert chemical energy (glucose) into mechanical and thermal energy.
Step-by-step explanation:
Muscles are responsible for movement in the body. They are made up of specialized cells called muscle fibers, which contain proteins that can contract and generate force. When you move your body, your muscles contract and generate mechanical energy that enables movement. At the same time, the chemical energy stored in glucose molecules is broken down through a process called cellular respiration, which releases heat energy. This heat energy is then dispersed throughout your body, raising your body temperature. Therefore, when your body moves, it uses both mechanical and thermal energy generated by muscle contraction and glucose metabolism.
