This tutorial demonstrates the use of the Pendulum Lab Phet simulation, covering simple harmonic motion, energy conservation, and factors affecting pendulum oscillations. It provides step-by-step instructions on using the simulation tools, measuring oscillations, and calculating time periods. The tutorial also explores advanced features like velocity and acceleration vectors, and offers assignments for further exploration.
