Principles of Energy and Energy Transfers

What type of energy is stored in an object due to its motion?

• Gravitational potential energy

• Elastic potential energy

• Kinetic energy

• Chemical energy

Which energy type is associated with the position of an object in a gravitational field?

• Thermal energy

• Chemical energy

• Gravitational potential energy

• Electrical energy

When a system changes, what happens to the energy within it?

• It is destroyed

• It increases indefinitely

• It remains constant

• It is transferred to other energy types or stores

What happens to the kinetic energy of a ball as it reaches its maximum height?

• It remains constant

• It is converted to gravitational potential energy

• It increases

• It disappears

When a car brakes, what happens to its kinetic energy?

• It is converted to internal energy

• It remains as kinetic energy

• It is lost

• It is stored as chemical energy

What is the result of repeatedly hitting a piece of metal with a hammer?

• The metal cools down

• The metal becomes electrically charged

• The metal's internal energy decreases

• The metal's temperature increases

In the process of boiling water in a kettle, what type of energy is primarily transferred to the water?

• Chemical energy

• Gravitational potential energy

• Kinetic energy

• Thermal energy
