Energy Concepts Quiz

How can you relate the concept of kinetic and potential energy in a real-life situation?

• By memorizing their definitions only.

• By observing how energy changes form, such as a swinging pendulum.

• By ignoring energy changes in daily life.

• By only reading about energy in textbooks.

What happens to the energy of a pendulum as it swings back and forth?

• The energy stays the same at all points.

• Potential energy changes into kinetic energy, and kinetic energy changes back into potential energy.
