Question

dec. 2 thermal energy day 1 notes practice
kinetic energy refers to energy that is ______.
potential energy
kinetic energy
○ stored
○ at rest
○ in motion
○ being created

Explanation:

Kinetic energy is the energy of motion. The diagram shows the bow - arrow system: when the arrow is moving (kinetic energy), while potential energy is stored (like the drawn bow). Among the options, "in motion" matches the definition of kinetic energy. "Stored" is potential energy, "at rest" is not motion, and "being crossed" is irrelevant.

Answer:

C. in motion
