Kinetic and Potential Energy

What is the relationship between kinetic energy and potential energy in a pendulum swing?

• Kinetic energy is highest at the top of the swing.

• Potential energy is converted into kinetic energy as the pendulum falls.

• Kinetic energy remains constant throughout the swing.

• Potential energy is highest when the pendulum is at the lowest point of its swing.

According to the law of conservation of energy, what happens to the total amount of energy in a closed system?

• It decreases over time.

• It increases when work is done on the system.

• It remains constant.

• It can be created or destroyed but not transferred.
