Key Points
- Simple Pendulum:
- A simple pendulum consists of a small metallic ball or a piece of stone suspended from a rigid stand by a thread.
- The metallic ball is termed as bob.
- A pendulum swings from one extreme position to another and comes back to the same position, this completes one oscillation.
- The pendulum is said to be at maximum displacement when it is at an extreme position.
- One oscillation can also be defined as the pendulum starting from the mean position, going to one extreme, and coming back to the same mean position.
- The time period for an oscillation to compete is called the time period and the inverse of the time period is the frequency.
- So, Potential energy is maximum at maximum displacement position or extreme positions P and T.
- Kinetic energy is minimum at the equilibrium position. The equilibrium position is the mean position.
- The pendulum has minimum potential energy at position R.
