Rollercoaster Energy

What type of energy is stored as the roller coaster climbs to the top of the lift hill?

• Thermal energy

• Kinetic energy

• Potential energy

• Mechanical energy

What happens to the potential energy as the coaster descends the first drop?

• It remains constant

• It converts into kinetic energy

• It increases further

• It is lost as heat

What causes the roller coaster to slow down during the ride?

• Magnetic fields

• Friction and air resistance

• Decrease in mass

• Increase in potential energy

How do magnetic brakes help in stopping the roller coaster?

• By increasing kinetic energy

• By pushing the train backwards using magnetic fields

• By generating electricity

• By converting kinetic energy into potential energy

What role do friction brakes play in stopping the roller coaster?

• They cool down the train

• They reduce the coaster's potential energy

• They clamp against metal plates on the train to slow it down

• They generate more kinetic energy
