Question

Explain the energy transformation that occurs when a person exercises.

Group of answer choices

Magnetic energy transforms into mechanical energy.

Electrical energy transforms into mechanical energy.

Thermal energy transforms into electrical energy.

Mechanical energy transforms into thermal energy.

Answer 1

Mechanical energy transforms into thermal energy.

Explanation: muscles use chemical energy (from food/ATP) to produce mechanical work when you exercise, and because muscles are inefficient some of that work is dissipated as heat. That waste heat raises your body temperature — a mechanical → thermal energy transformation.
