1 answer

Here are the answers to your questions based on the principles of potential energy and kinetic energy in physics:

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

    • Answer: 10 m
      • Potential energy is greatest at the highest point (10 m) because it is calculated as \(PE = mgh\), where \(m\) is mass, \(g\) is the gravitational constant, and \(h\) is height.

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

    • Answer: just below 10 m
      • Kinetic energy reaches its maximum just before the ball hits the ground as it converts potential energy into kinetic energy during its descent.

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

    • Answer: Potential energy is decreasing.
      • As the ball falls, its height decreases, leading to a decrease in potential energy.

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

    • Answer: Kinetic energy is increasing.
      • As the ball falls and accelerates due to gravity, its speed increases, resulting in an increase in kinetic energy.

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

    • Answer: Total energy is staying the same.
      • In the absence of air resistance or other external forces, the total mechanical energy (the sum of potential and kinetic energy) remains constant throughout the fall (conservation of energy).
