Formula for the period T of simple pendulum

The formula for the period $T$ of a simple pendulum is:

$$T = 2\pi \sqrt{\frac{L}{g}}$$

Where:

• $T$ is the period of oscillation (the time taken for one complete swing).
• $\pi$ (pi) is a mathematical constant, approximately 3.14159.
• $L$ is the length of the pendulum from the pivot point to the center of mass of the bob.
• $g$ is the acceleration due to gravity.
