Questions and Answers

What happens to kinetic energy when gravitational potential energy increases in this experiment?

  • Kinetic energy must go down. (correct)
  • Kinetic energy increases proportionally.
  • Kinetic energy remains constant.
  • Kinetic energy changes randomly.
  • What does the experiment suggest about the total amount of energy throughout the process?

  • It is only conserved during the descent.
  • It remains constant over time. (correct)
  • It must be balanced by introducing additional energy.
  • It can change depending on external factors.
  • In the experiment with four different tracks, how would the energy conservation principle affect the ball bearing's distance from the table?

  • The track with the highest potential energy will have the ball land closest.
  • The track that minimizes potential energy maximizes distance traveled. (correct)
  • Distance is independent of the energy levels.
  • All tracks will result in the same distance regardless of shape.

    Study Notes

    Conservation of Energy

    • Energy is conserved during movement.
    • Gravitational Potential Energy (GPE) changes with height
    • Kinetic Energy (KE) changes with speed.
    • The total energy (GPE +KE) stays the same.
    • Different tracks affect the distance a ball bearing travels when released from the same height.
