How does energy transfer occur?

• Energy transfer occurs when energy moves from one object or system to another.

• Energy transfer occurs only in electrical systems.

• Energy transfer is the process of energy being created.

• Energy transfer happens when energy is lost to the environment.

What is kinetic energy?

• The energy of an object at rest.

• The energy of an object in motion.

• The energy stored in an object due to its position.

• The energy released during a chemical reaction.
