The experiment:

Procedure:We set out pendulum to 30 degrees and then dropped it and measured the time it took for the bob to go back and forth 10 times. We then recorded the times and repeated that process five times for each different weight and length.

Introduction:

The goal of this physics lab is to model the motion of a pendulum mathematically. The pendulum is a set amount of mass attached to a rope of a set length. It is also suspended from a fixed length. In our experiment, we manipulated the mass of the pendulum "bob" and the length of the rope respectively. The pendulum, when displaced at a certain angle and let go, follows a "to-and-fro" swinging path and eventually comes to a stop in its equilibrium position. Our goal was to measure this swinging motion in terms of time to go back and forth 10 times. Then we will mathematically model this motion.

Theory:

After finishing the physics lab and collecting data, we can come up with an equation for a simple pendulum. The equations for a simple pendulum show how to find the frequency and period of motion. The period of motion for a pendulum is how long it takes to swing back and forth, measured in seconds. The equation for the period of a simple pendulum starting at a small angle alpha isT = 2(L/g). Where T is the period in seconds (s). L is the length of the rod or wire in meters or feet. g is the acceleration due to gravity.

Experimental Details:

The apparatus we used to conduct our experiment was a tall, metal structure with a piece (arm) sticking out from the top. At the end of this arm, there was a hanging string that held the bob which we used to calculate the time of one period. We used a protractor to set our drop angle at exactly 30 degrees.

Procedure:We set out pendulum to 30 degrees and then dropped it and measured the time it took for the bob to go back and forth 10 times. We then recorded the times and repeated that process five times for each different weight and length.

Data:

Looking at the data we have from our experiment, our greatest source of error came from the reaction time between dropping the bob and beginning the timer. However, our values of precision were still rather low. The largest value of precision we recorded in this experiment was 0.03s. We did however notice some oddities in our graphs and the way these graphs represent the data.
