Question

A woman runs. What main energy conversion occurs?

Answer 1

When a woman runs, the main energy conversion that occurs is the transformation of chemical energy into kinetic energy. The chemical energy stored in the food she has consumed is converted into kinetic energy that powers her movement. Additionally, during the running process, some of this energy may also be converted into thermal energy due to metabolic processes and friction, leading to the production of heat. However, the primary focus is on the conversion from chemical energy to kinetic energy.
