To answer your question about the pendulum bob at points 1 and 2, we need to consider its position and the forces acting on it at these points.
-
At the highest point (Point 1): When the pendulum bob is at the highest points of its swing (Point 1), it has maximum potential energy and minimum kinetic energy. The speed of the bob is zero at this point since it momentarily stops before reversing direction.
-
At the lowest point (Point 2): When the pendulum bob is at the lowest point of its swing (Point 2), it has maximum kinetic energy and minimum potential energy. Here, the speed of the bob is at its highest because it has converted the potential energy gained while rising back into kinetic energy.
True Comparisons:
- Speed: The pendulum bob is moving fastest at Point 2 and is momentarily at rest at Point 1.
- Energy: The potential energy is highest at Point 1 and lowest at Point 2, while the kinetic energy is highest at Point 2 and lowest at Point 1.
If you need more specific comparisons or have particular aspects in mind (like forces, energy types, etc.), please let me know!
