How is potential energy stored in the snowboarder-Earth system?

• In the gravitational field

• In the snowboard

• In the air

• In the snow

How is energy stored in the snowboarder-Earth system when the snowboarder is pushed away from Earth by the ski lift?

• As kinetic energy in the snowboard.

• As potential energy in the gravitational field.

• As thermal energy in the air.

• As sound energy in the environment.

What role does gravity play in the movement of a snowboarder down a hill?

• It slows the snowboarder down.

• It converts potential energy into kinetic energy.

• It has no effect on the snowboarder.

• It stores energy in the snowboard.

What force is responsible for transferring energy into the skydiver-Earth system?

• Friction

• Magnetism

• Gravity

• Electricity

What type of energy is stored in the gravitational field between the skydiver and Earth before the skydiver starts to fall?

• Kinetic energy

• Thermal energy

• Potential energy

• Chemical energy

How does the gravitational force affect the skydiver as they fall?

• It slows them down

• It converts potential energy into kinetic energy

• It makes them float

• It stops them from falling

What happens to the potential energy of a skydiver when they fall towards Earth?

• It is converted into kinetic energy.

• It remains as potential energy.

• It disappears completely.

• It is converted into thermal energy.
