Exploring Newton's First Law of Motion

What does Newton's First Law of Motion state?

• Energy cannot be created or destroyed.

• For every action, there is an equal and opposite reaction.

• Objects at rest will stay at rest, and objects in motion will stay in motion.

• Force equals mass times acceleration.

What is the Hero Engine filled with?

• Sand

• Air

• Oil

• Water

What tool is used to heat the water in the Hero Engine?

• A lighter

• A blowtorch

• A candle

• A matchstick

What is produced when the water in the Hero Engine boils?

• Steam

• Smoke

• Mist

• Bubbles

What causes the Hero Engine to start spinning?

• The heat from the blowtorch

• The steam escaping through the pipes

• The shape of the pipes

• The weight of the water

According to Newton, how long would the Hero Engine spin in the absence of external forces?

• Forever

• For a few minutes

• Until the water runs out

• Until it cools down

Which of the following is NOT a force acting on the Hero Engine on Earth?

• Gravity

• Magnetism

• Friction

• Air resistance

What would happen to the Hero Engine in space?

• It would not spin at all.

• It would spin forever unless acted upon by an external force.

• It would stop spinning immediately.

• It would spin faster.

Which of the following is an example of an external force that could stop the Hero Engine in space?

• Collision with a spaceship

• Gravity

• Air resistance

• Friction

What is the main takeaway from the Hero Engine experiment?

• Newton's laws apply both on Earth and in space.

• Blowtorches are useful tools.

• Steam can create motion.

• Water boils at high temperatures.
