This project explores gravitational acceleration through a pendulum experiment. By measuring pendulum swing times and calculating gravitational acceleration, students will gain a deeper understanding of physics laws and the effects of gravity on motion.
If I measure the period of a pendulum, then I can calculate gravitational acceleration using the length of the pendulum.

Attach the weight to one end of the string.
Secure the other end to a fixed point to create a pendulum.
Measure the length of the pendulum from the pivot to the weight.
Pull the pendulum to a small angle and release it.
Use the stopwatch to time multiple swings.
Calculate the average period of the swings.
Use the formula to calculate gravitational acceleration.
Present findings in a report format.
The calculated gravitational acceleration should be close to the standard value of approximately 9.81 m/s², demonstrating the principles of pendulum motion.
