Question

What happens to the potential energy as the pendulum swings from point A to point E?

Question 4 options:

Potential energy increases.


Potential energy decreases.


Potential energy increases then decreases.


Potential energy decreases then increases.

Answer 1

In the context of a pendulum swinging from its highest point (point A) to its lowest point (point E), the potential energy behaves as follows:

- At point A, the pendulum has maximum potential energy because it is at its highest elevation.
- As the pendulum swings down towards point E, the potential energy decreases because the height of the pendulum is decreasing.
- When the pendulum reaches point E (the lowest point), it has minimum potential energy.

So the correct option is: **Potential energy decreases.**
