Understanding the Simple Pendulum

Introduction to the Simple Pendulum

• The simple pendulum consists of a string or rod and a mass at its end, exhibiting pendular motion that follows the same laws as simple harmonic motion.

Key Equations of Motion

• The equations governing simple harmonic motion are introduced, including amplitude (A), angular frequency (ω), and phase shift (φ).

• The angular frequency for a pendulum is derived as ω = √(g/L), where g is gravity and L is the length of the string.

Period of the Pendulum

• By combining previous equations, it’s established that the period (T) of a pendulum is T = 2π√(L/g), indicating that mass does not influence the period.

Experimental Demonstration

• An experiment is proposed to demonstrate that mass does not affect the period by using two different masses: one 150 grams and another 10 grams.

Observations from Experiments

• Both masses are released from an angle of 60 degrees, showing identical movement patterns, confirming that mass has no effect on pendular motion.

Further Experimentation with Length Variations

• A second experiment will compare periods using equal masses at different lengths: one at 0.5 meters and another at 1 meter to observe differences in periods based on length alone.
