The formula shown in the image is used to calculate the gravitational acceleration \( g \) on Earth. The formula given is:

\[
g = l \left( \frac{2\pi}{T} \right)^2
\]

where:
- \( g \) represents the gravitational acceleration,
- \( l \) denotes the length of a pendulum,
- \( T \) is the period of the pendulum (the time it takes for one complete oscillation).

This equation is derived from the properties of a simple pendulum, where the gravitational acceleration can be determined based on the period of oscillation for a pendulum of known length. The relationship \( T = 2\pi \sqrt{\frac{l}{g}} \) is commonly used, and rearranging this gives the formula in the image to solve for \( g \).
