Finding the acceleration due to Gravity by simple pendulum method

This Experiment is to be performed at home with equipment that is expected to be available to you. Take pictures of the experimental setup and upload with your report. Make a video of the experiment being performed, and upload with your report

OBJECTIVE

The purpose of this experiment is to determine the acceleration due to gravity by using a simple pendulum.

MATERIALS

1. String (Preferably a tread) 2. Small Mass

3. Stopwatch (Use your Phone) 4. Support for Pendulum

5. ruler or Tape Measure

INTRODUCTION

A point mass attached to a light string forms a simple pendulum. When the mass is pulled to one side and let go, it swings back and forth. The time taken for one complete vibration, i.e. from one extreme to the other, and back to the first, is called the Time Period, T. The time period depends on the acceleration due to gravity, g, and the length of the pendulum. By measuring the length of the pendulum and the time period, the value of g can be found from the equation:
