To determine the correct comparison of the pendulum bob at points 1 and 2, we need to consider the concepts of potential energy and kinetic energy.
- Potential Energy (PE): A pendulum has the highest potential energy at its highest points (the endpoints of its swing) and the lowest potential energy at its lowest point (the lowest point in its arc).
- Kinetic Energy (KE): Conversely, the kinetic energy of the pendulum bob is highest at its lowest point (as it is moving fastest there) and lowest at the endpoints when it momentarily stops before reversing direction.
Based on the principles of energy conservation in a pendulum:
- If point 1 and point 2 are at the highest positions of the swing, then:
- The pendulum has its highest potential energy at both point 1 and point 2 (since it is at the highest positions in the swing) and its lowest kinetic energy.
- If point 1 and point 2 are at the lowest point:
- The pendulum would have the lowest potential energy at these points and its highest kinetic energy.
With these concepts in mind, the correct statement would likely be: "The pendulum has its highest potential energy at point 1 and point 2."
This is true if points 1 and 2 refer to the endpoints of the pendulum's swing. If points 1 and 2 refer to the lowest position, then none of the responses would be correct. Please confirm the specifics of the positions to identify the exact answer correctly.
