If you roll the bowling ball so it moves faster, what happens when it hits the pins?

Multiple Choice

Which object has the greater speed?

• A (started higher)

• B (started lower)

• Both have the same speed

• Neither has speed

Open Ended

Suppose you roll a volleyball down the alley instead of a bowling ball. If the volleyball travels at the same speed as a bowling ball, do you think it will send pins flying as far? Why or why not?

Multiple Choice

Which ball has the greatest kinetic energy?

• A (more mass)

• B (less mass)

• Both have the same kinetic energy

• Neither has kinetic energy

Open Ended

What is the difference between the energy of a moving bowling ball and a stationary bowling ball?

Multiple Choice

What is potential energy?

• The energy stored in an object because of its position

• The energy of motion

• The energy released during a chemical reaction

• The energy produced by electricity

Multiple Choice

Which ball has the greatest potential energy due to its position?

• Ball A

• Ball B

• Both have the same

• Neither

Open Ended

Explain why Ball A has more potential energy than Ball B in the given diagram.

Multiple Select

Which of the following statements about potential energy are correct?

• Potential energy is stored energy.

• Potential energy is measured in Joules (J).

• Potential energy increases with height and mass.

• Potential energy is the energy of motion.

Open Ended

How do height and mass affect the potential energy of an object?

Open Ended

What happens if the bowling ball falls off the table?

Open Ended

Explain how the total amount of energy remains constant when a bowling ball is released and begins to slow down.

Multiple Choice

• Kinetic Energy

• Potential Energy

• Thermal Energy

• Sound Energy

Multiple Select

Which of the following statements are true about the energy of the cart at the top of the ramp?

• The cart has maximum kinetic energy.

• The cart has maximum potential energy.

• The total mechanical energy is the sum of kinetic and potential energy.

• The cart has zero energy.

Multiple Choice

As potential energy increases, what happens to kinetic energy?

• It increases.

• It decreases.

• It stays the same.

• It disappears.

Multiple Choice

What happens to the potential energy (PE) and kinetic energy (KE) of a ball as it falls and bounces up again?

• PE increases, KE decreases

• PE decreases, KE increases

• Both PE and KE increase

• Both PE and KE decrease

Multiple Choice

Which of the following best describes the transformation of energy in a roller coaster as it moves along the track?

• Potential energy is always greater than kinetic energy.

• Kinetic energy is always greater than potential energy.

• Potential and kinetic energy transform into each other, but total energy remains constant.

• Total energy decreases as the roller coaster moves.

Open Ended

Explain the relationship between potential energy and kinetic energy between points 1 and 2 in the roller coaster diagram.

Multiple Choice

Where on the roller coaster is the total energy of the system the highest?

• At the highest point (1)

• At the lowest point (3)

• Phone falling off the table

Open Ended

How would you explain the difference between potential energy and kinetic energy in your own words?

Multiple Choice

What is the Law of Conservation of Energy?

• Energy can be created and destroyed

• Energy cannot be created or destroyed, it transforms from one form to another

• Energy is always lost as heat

• Energy only exists in living things
