Objective:

Calculate the value of gravitation acceleration on different planets. To calculate the value of the gravitational acceleration we will use an online version of a simple pendulum.

Virtual pendulum and stopwatch (https://phet.colorado.edu/en/simulation/pendulum-lab)

Theory:

The time it takes a simple pendulum to make a complete swing (back and forth) is called its period(T).If the pendulum is allowed to swing through a small angle, the period is given by the equation:
