Here are the answers to your questions based on the principles of physics related to potential energy (PE) and kinetic energy (KE):

Question 1: a. At which position is the potential energy the greatest?

  • Response: 6 m
    (Potential energy is highest when the object is at the highest position, which is 6 meters in this case.)

Question 2: b. At what position is the kinetic energy the greatest?

  • Response: just above 0 m
    (Kinetic energy is greatest just before the object reaches the ground, so just above 0 meters.)

Question 3: c. What is happening to potential energy as the ball is falling?

  • Response: Potential energy is decreasing.
    (As the apple falls, its height decreases, leading to a decrease in potential energy.)

Question 4: d. What is happening to kinetic energy as the ball is falling?

  • Response: Kinetic energy is increasing.
    (As the apple falls and speeds up, its kinetic energy increases.)

Question 5: e. What is happening to total energy as the ball is falling?

  • Response: Total energy is staying the same.
    (In a closed system, the total mechanical energy (potential + kinetic) remains constant as long as no external forces do work on it, assuming air resistance is negligible.)
