How does human power work?





Question:

Answer: Human energy is derived from the food we eat. The complex carbohydrates in food are broken down by enzymes in our stomach to help create usable energy for our bodies. The most common way to use human power is by making our muscles do mechanical work by pushing or pulling something. We can use the energy from that force to do anything from lifting objects, pulling levers, or even powering electric generators.

Another form of human power is in the form of heat we give off in our normal metabolic processes (the consumption and use of food by our bodies). You could think of each person as a mini heater giving off heat energy at some rate all the time.
