(1 point)
•
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 from digestion of food provides energy for the runners m
ergy
Mechanical energy changes into thermal energy because the energy from motion creates heat in the air around the runner.

Answer 1

The correct answer is:
Mechanical energy changes into thermal energy because the energy from motion creates heat in the air around the runner.
