Rollercoaster energy

What type of energy is stored in a roller coaster train as it climbs a lift hill?

• Kinetic energy

• Thermal energy

• Potential energy

• Mechanical energy

When does a roller coaster train typically achieve its fastest speed?

• At the top of the highest hill

• At the bottom of the first drop

• While climbing the lift hill

• During the final brake run

Which of the following factors causes a roller coaster to lose energy during its ride?

• Gravity

• Magnetic forces

• Friction and wind resistance

• The height of the hills

Are you enjoying the video lesson?

• Yes

• No

How does Kingda Ka, an untraditional roller coaster, gain the energy needed to overcome its tall hill?

• It uses a long lift hill to build potential energy

• It relies solely on the force of gravity

• It uses a powerful launch system

• It generates energy through friction with the track

What type of energy is mechanical energy converted into when Kingda Ka's launch system accelerates the train?

• Potential energy

• Thermal energy

• Kinetic energy

• Chemical energy

What is the term for when a roller coaster train, like Kingda Ka, fails to make it over the main hill and rolls backward?

• Stall

• Rollback

• Recoil

• Reversal

If Kingda Ka is twice the height of Nitro, how does its potential energy at the top of its largest hill compare to Nitro's?

• It will have half the potential energy.

• It will have the same potential energy.

• It will have much more potential energy.

• It will have less kinetic energy.

What happens to a roller coaster train's energy and speed when more mass (like riders) is added to it?

• Both energy and speed decrease.

• Energy decreases, but speed increases.

• Both energy and speed increase.

• Energy increases, but speed decreases.
