Here are the answers to your questions based on the principles of energy conservation in a falling ball scenario:

Question 1

a. At which position is the potential energy the greatest?

  • Answer: 10 m

Question 2

b. At what position is the kinetic energy the greatest?

  • Answer: just above 0 m

Question 3

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

  • Answer: Potential energy is decreasing.

Question 4

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

  • Answer: Kinetic energy is increasing.

Question 5

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

  • Answer: Total energy is staying the same.

Explanation:

  • As the ball falls, its potential energy decreases because it is losing height. Conversely, kinetic energy increases as the ball falls and speeds up. The total mechanical energy (potential + kinetic) remains constant if we assume no air resistance, hence it stays the same.
