Here are the answers to your questions about the pendulum:
a. When the pendulum is held at the top of its swing, what type of energy does it have?
- **Potential energy**
b. As the pendulum swings freely, what is happening to its energy?
- **PE converts to KE as it falls, and then KE converts to PE as it rises**
c. When are kinetic energy and potential energy equal in magnitude (equal in amount)?
- **They are equal half-way between the top position and the bottom position.**
These responses reflect the energy transformations that occur in a pendulum as it swings.
