Simple Pendulum Experiment Concepts

This video tutorial covers a practical session on conducting a simple pendulum experiment. It begins with an introduction to the experiment's aim, followed by a list of required materials. The video explains the theory behind a simple pendulum, including its working principles and the formula for calculating the time period. It also demonstrates how to operate a stop clock for accurate measurements. The procedure section provides a detailed, step-by-step guide to performing the experiment, including measuring and marking the thread, setting up the pendulum, and recording oscillations. Observations and calculations are discussed, highlighting the importance of accuracy and error analysis. The video concludes with precautions to ensure reliable results and a summary of findings.
