The only force responsible for the oscillating motion of the pendulum is the x -component of the weight, so the restoring force on a pendulum is: F = − m g sin. . θ. For angles under about 15 °, we can approximate sin θ as θ and the restoring force simplifies to: F ≈ − m g θ. Thus, simple pendulums are simple harmonic oscillators ...

Thus, the motion of a simple pendulum is a simple harmonic motion with an angular frequency, ω = √ g L ω = g L, and linear frequency, f = 1 2π√ g L f = 1 2 π g L. The time period is given by, T = 1 f = 2π√L g T = 1 f = 2 π L g. Performing dimension analysis on the right side of the above equation gives the unit of time.

The period of a simple pendulum is T = 2π L g−−√ T = 2 π L g. L is equivalent to the expression 1 h k2 +h2− −−−−−√ 1 h k 2 + h 2, which has a value found graphically as explained in procedure 4 (above). Using this value for L L compute L T2 L T 2, and find g g from the expression: g = 4π2 L T2 g = 4 π 2 L T 2.
