What happens to kinetic energy when gravitational potential energy increases in this experiment?
What happens to kinetic energy when gravitational potential energy increases in this experiment?
- Kinetic energy must go down. (correct)
- Kinetic energy increases proportionally.
- Kinetic energy remains constant.
- Kinetic energy changes randomly.
What does the experiment suggest about the total amount of energy throughout the process?
What does the experiment suggest about the total amount of energy throughout the process?
- It is only conserved during the descent.
- It remains constant over time. (correct)
- It must be balanced by introducing additional energy.
- It can change depending on external factors.
In the experiment with four different tracks, how would the energy conservation principle affect the ball bearing's distance from the table?
In the experiment with four different tracks, how would the energy conservation principle affect the ball bearing's distance from the table?
- The track with the highest potential energy will have the ball land closest.
- The track that minimizes potential energy maximizes distance traveled. (correct)
- Distance is independent of the energy levels.
- All tracks will result in the same distance regardless of shape.

Conservation of Energy
Conservation of Energy
Total energy in a closed system remains constant; it can change forms (like kinetic to potential) but is never created or destroyed.
Kinetic Energy
Kinetic Energy
Energy of motion; depends on mass and speed.

Study Notes
Conservation of Energy
- Energy is conserved during movement.
- Gravitational Potential Energy (GPE) changes with height
- Kinetic Energy (KE) changes with speed.
- The total energy (GPE +KE) stays the same.
- Different tracks affect the distance a ball bearing travels when released from the same height.
