Then proceeded to find experimental values of T with two different methods of measurement: Because of the uncertainty in gathering data this must also be applied to the theoretical value of T with the following equation.

Next we measured the period with a digital stopwatch. The Simple Pendulum is a basic time-keeping apparatus.

We recorded this information and calculated the Standard Deviation of the average. Once the pendulum starts swinging the values are recorded in a table on the computer screen.

Once finding the theoretical period we when can compare it to experimental measured value we found of the period.

A weight is suspended on a length of string which in turn is attached to a frictionless pivot so it can swing freely. The equipment used in this experiment was a simple pendulum, a wooden meter stick, a PASCO photogate timer, and a digital stopwatch.

In gathering the experimental data there will be a degree of uncertainty associated with the gathered values. The PASCO photogate timer records the period of the pendulum directly with the senor at the base of the pendulum and the sensor at precisely the center of where the weight hangs when not swinging.

With these equations we can compare the theoretical value of T with experimental values of T and can find the statistical uncertainly of our results. We first used the wooden meter stick to measure the string from where it was tied at the pivot to around the center of the weight and recorded this length, L, in meters.

Next we calculated the theoretical period of our simple pendulum. One person started the pendulum swinging and another timed 5 oscillations with the stopwatch. More Essay Examples on Experiment Rubric A Period of motion is a physical quantity associated with any cyclical natural phenomenon and is defined as one complete cycle of motion.

If the theoretical and experimental values are equal within the uncertainty ranges we can say that the theory has been proven valid.

We divided the time by 5 and recorded it. The time period it takes to complete one swing is determined by the theoretical equation derived from the Physical Theory of Repeating Motions, aka Simple Harmonic Motion.Lab Report: The Simple Pendulum Essay Gain insight on how scientists come to understand natural phenomena through theoretical and experimental data by determining the Period of a Simple Pendulum - Lab Report: The Simple Pendulum Essay introduction.

Pendulum Lab Essay Sample. Abstract Intent: To conduct an experiment to prove the yielding support distance is directly proportional to the period. To conduct a lab experiment for the oscillations of a pendulum with a yielding support 2.

investigate the simple pendulum 3. To prove that the distance (m) is directly proportional to period.

The objective of this experiment is to observe the motion of a simple pendulum, study simple harmonic motion, determine some factors that affect the period of a pendulum, and measure the value of acceleration due to gravity by use of a simple pendulum.

Simple Pendulum PURPOSE The purpose of this experiment is to study how the period of a pendulum depends on length, mass, and amplitude of the swing. The pendulum suspension was made sure to be friction-free so that the wood blocks could provide a point of suspension for the string.

The angle at which the pendulum is drawn out to should be small. The smaller the angle, the closer the harmonic motion it will behave because the restoring force is acting tangent to the arc – the pendulum.

The period of oscillation of a simple pendulum depends on the length and is directly proportional to the square root of the length. Moreover, we know that the period of oscillation is independent of the amplitude when the amplitude is within small limits (length remaining constant).
