  • Q8
    What is the relationship between kinetic energy and the mass of an object?
    Kinetic energy remains constant regardless of mass
    Kinetic energy decreases with an increase in mass
    Mass has no effect on kinetic energy
    Kinetic energy increases with an increase in mass
    30s
  • Q9
    Which of the following best describes the law of conservation of energy?
    Energy can only be converted from one form to another.
