How does the potential energy of an object change if its height triples?

• Increases

• Remains the same

• Becomes negative

• Decreases

What is the relationship between kinetic and potential energy?

• Potential energy is a form of thermal energy.

• They are completely unrelated to each other.

• Kinetic energy is a form of potential energy.

• They are both forms of mechanical energy.

Can an object have both kinetic and potential energy at the same time? If yes, provide an example.

• Yes, but only in a vacuum

• No, it's not possible

• Yes

• Yes, but only in outer space
