What is the unit used to measure energy?

• Newton

• Joule

• Watt

• Hertz

Which type of potential energy is stored in a stretched rubber band?

• Gravitational

• Elastic

• Chemical

• Nuclear

What kind of energy does a moving skateboard have?

• Nuclear

• Kinetic

• Chemical

• Potential

According to the law of conservation of energy, energy can be:

• Both created and destroyed

• Neither created nor destroyed, only transferred

• Destroyed but not created

• Created but not destroyed

How does potential energy change as you go down a hill on a bicycle?

• Becomes thermal energy

• Remains the same

• Increases

• Decreases

What is kinetic energy?

• Energy stored in stationary objects

• Energy of motion

• Energy absorbed from the sun

• Energy released during chemical reactions

How do you calculate kinetic energy?

• Mass plus velocity

• Mass times velocity

• Half the mass times velocity squared

• Velocity divided by mass

If the mass of an object is doubled, how does this affect its kinetic energy, assuming velocity remains constant?

• It halves the kinetic energy

• It doubles the kinetic energy

• It does not affect the kinetic energy

• It quadruples the kinetic energy

Which of the following best describes the relationship between mass and kinetic energy?

• Inversely proportional

• Directly proportional but not linear

• Directly proportional and linear

• No relationship

What happens to the kinetic energy if the velocity of an object is doubled?

• It doubles

• It quadruples

• It triples

• It remains the same
