Questions and Answers

What effect does increasing the mass of a moving object have on its kinetic energy?

  • It depends on the object's velocity.
  • It increases the kinetic energy. (correct)
  • It has no effect on kinetic energy.
  • It decreases the kinetic energy.

    • How is the peak force of a collision related to the kinetic energy of the objects involved?

  • Higher kinetic energy results in higher peak forces. (correct)
  • There is no relation between kinetic energy and peak forces.
  • Higher kinetic energy results in lower peak forces.
  • Lower kinetic energy results in higher peak forces.

    • Which of the following would most likely lead to a greater increase in kinetic energy?

  • Doubling the mass of an object.
  • Holding mass constant and increasing speed by 25%.
  • Doubling the speed of an object. (correct)
  • Increasing the object's speed by 50%.
