Question

Ch 11.29 - A person is walking on level ground at constant speed. What energy transformation is taking place?

A. Chemical Energy is being transformed into thermal energy B. Chemical Energy is being transformed into Kinetic energy C. Chemical Energy is being transformed to kinetic energy and thermal energy D. Chemical Energy and thermal energy are being transformed to kinetic energy

Answer 1

The energy transformation that is taking place when a person is walking on level ground at constant speed is kinetic energy being transformed from chemical energy.

Step-by-step explanation:

The energy transformation that is taking place when a person is walking on level ground at constant speed is kinetic energy being transformed from chemical energy.

When we consume food, our body breaks down the chemical energy in the food through metabolism, converting it into a usable form of energy called ATP. This ATP is then used by our muscles to perform work, which in this case is walking.

So, the correct option is B. Chemical Energy is being transformed into Kinetic energy.
