Question

A woman runs as shown. What main energy conversion occurs? (1 point) Responses Mechanical energy changes into thermal energy because the energy from motion creates heat in the air around the runner. Mechanical energy changes into thermal energy because the energy from motion creates heat in the air around the runner. Thermal energy changes into mechanical energy because heat provides energy for motion. Thermal energy changes into mechanical energy because heat provides energy for motion. Mechanical energy changes into chemical energy as the kinetic energy from motion creates reactions in the surrounding air. Mechanical energy changes into chemical energy as the kinetic energy from motion creates reactions in the surrounding air. Chemical energy changes into mechanical energy because energy from digestion of food provides energy for the runner’s motion. Chemical energy changes into mechanical energy because energy from digestion of food provides energy for the runner’s motion. Skip to navigation

Answer 1

The correct response is: Chemical energy changes into mechanical energy because energy from digestion of food provides energy for the runner’s motion.

When a woman runs, the energy stored in her body from the food she has eaten (chemical energy) is converted into the mechanical energy that powers her movement.
