Simple Pendulum Lab
Explore how pendulum length and starting angle affect its motion and time period.
๐ฏ Aim of Experiment
To investigate the motion of a simple pendulum and understand how changing its length affects the time required for one complete oscillation.
๐ง Theory
A simple pendulum consists of a small mass called a bob suspended from a fixed point by a light string. When displaced and released, gravity causes the bob to oscillate around its equilibrium position.
T = Time period
L = Pendulum length
g = Acceleration due to gravity
๐ Observation Table
Change the length, run the experiment and record your results.

๐ What Should You Observe?
Try increasing the pendulum length. You should notice that the pendulum swings more slowly.
A longer pendulum has a larger time period, while a shorter pendulum oscillates faster.
๐ก Remember
For relatively small angles, the time period depends mainly on the length of the pendulum and gravitational acceleration.
Changing the bob’s mass does not appear in the ideal simple-pendulum period equation.
