  • Q8
    What happens to energy when it is converted to heat?
    It becomes kinetic energy
    It is stored for later
    It is often considered lost
    It increases in value

  • Q9
    Which of the following is a renewable energy source?
    Coal
    Uranium
    Wind energy
    Natural Gas
    30s
  • Q10
    In the example of lifting a ball, how is power calculated?
    Power = Work - Time
    Power = Work x Time
    Power = Work / Time
    Power = Work + Time

  • Q11
    What happens to energy during a transformation?
    It disappears
    It loses all properties
    It becomes heavier
    It can be changed from one form to another
    30s
  • Q12
    What type of energy is produced when you eat food?
    Sound energy
    Kinetic energy
    Chemical energy
    Radiant energy

  • Q13
    What is the relationship between work and energy?
    Energy cannot do work
    They are equivalent; the amount of work done equals the amount of energy used.
    They are independent
    Work is a type of energy
    30s
  • Q14
    How do you calculate power?
    Work done divided by time taken
    Force applied divided by distance
    Energy lost per second
    Distance moved per unit of time
