Here are the answers to your questions regarding the apple falling from a window ledge:

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

  • Response: 6 m

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

  • Response: just above 0 m

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

  • Response: Potential energy is decreasing.

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

  • Response: Kinetic energy is increasing.

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

  • Response: Total energy is staying the same.

Explanation:

  • Potential energy is highest at the starting height (6 m) and decreases as the apple falls.
  • Kinetic energy increases as the apple falls and gains speed, peaking just before it hits the ground (just above 0 m).
  • The total mechanical energy (potential + kinetic) remains constant throughout the fall, assuming no air resistance or other energy losses.
