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.

Chemical energy changes into mechanical energy because energy from digestion of food provides energy for the runner’s motion

The main energy conversion that occurs in this scenario is:
Chemical energy changes into mechanical energy because energy from digestion of food provides energy for the runner’s motion.
This indicates that the energy stored in the food the runner has consumed (chemical energy) is converted into energy that enables her to run (mechanical energy).
