27.8: Sample lab report (Measuring g using a pendulum)
The experiment was conducted in a laboratory indoors. 1. Construction of the pendulum. We constructed the pendulum by attaching a inextensible string to a stand on one end and to a mass on the other end. The mass, string and stand were attached together with knots. We adjusted the knots so that the length of the pendulum was \(1.0000\pm0.0005 ...

Better accuracy from simple pendulums
Most of the items have only a minor effect on accuracy, but they add up. 1. If possible, enclose the pendulum in a case. A case protects the pendulum from the air currents of an open room, which will push the pendulum around and give erratic timing. Also, if possible, mount the pendulum in a separate case from the hour strike or chimes.

The linear displacement from equilibrium is s, the length of the arc.Also shown are the forces on the bob, which result in a net force of − m g sin θ − m g sin θ toward the equilibrium position—that is, a restoring force.
The Simple Pendulum
The period is completely independent of other factors, such as mass. As with simple harmonic oscillators, the period \(T\) for a pendulum is nearly independent of amplitude, especially if \(\theta \) is less than about \(\text{15º}\). Even simple pendulum clocks can be finely adjusted and accurate. Note the dependence of \(T\) on \(g\). If the ...
15.5: Pendulums
The angle θ θ describes the position of the pendulum. Using the small angle approximation gives an approximate solution for small angles, d2θ dt2 = − g Lθ. (15.5.1) (15.5.1) d 2 θ d t 2 = − g L θ. Because this equation has the same form as the equation for SHM, the solution is easy to find. The angular frequency is.
Simple pendulum review (article)
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 ...

Procedure (to determine acceleration due to gravity value using pendulum motion) Measure the effective length of the pendulum from the top of the string to the center of the mass bob. The length should be approximately 1 m. Move the mass so that the string makes an angle of about 5° with the vertical. Release the bob.

Pendulum Experiment
The Pendulum Experiment is an experiment about gravity. Pendulums (or pendula if we are being exact!) are a fascinating scientific phenomenon. For many years they have been used for keeping time. If you pull back a pendulum and then let it go, the time it takes to swing over and then return back to its starting position is one period.
