Energy Transfer and Kinetic Energy

Which of the following is true when investigating the transfer of potential energy into kinetic energy and a marble?

• The marble released from a distance of 5 centimeters will have the most potential energy transferred into kinetic energy, causing the marble to travel the farthest.

• The marble released from a distance of 15 centimeters will have the most potential energy transferred into kinetic energy, causing the marble to travel the farthest.

• he marble released from a distance of 5 centimeters will have the least potential energy transferred into kinetic energy, causing the marble to travel the farthest.

• he marble released from a distance of 15 centimeters will have the least potential energy transferred into kinetic energy, causing the marble to travel the farthest.

At which point in this system does the pendulum bob demonstrate minimum potential energy?

• 1

• 2

• 3

• 4

The higher the drop, the more energy you have.

• True

• False

Where on the track is the total energy of the system the highest?

• he system has the most energy at R, S, and T because energy cannot be created or destroyed, so the total energy remains constant.

• The system has the most energy at point T where it has maximum potential energy because all the kinetic energy has been destroyed.

• .

  The system has the most energy at point R where it has maximum kinetic energy because all the potential energy has been destroyed.

• The system has the most energy at point S, where energy has been created to make the kinetic and potential energies the same.
