A table was drawn to record the results and from this a graph was plot. We also measured the time for ten successive swings to further reduce the errors. 206Conclusion Sample-2004 206ConSam. For his pendulum experiments, Galileo seems to have compared the pendulums in pairs over the same time. Calculate the period of the pendulum, T. Remember the units. Galileo found that each pendulum has a constant period. their results to class as Part A of the experiment. For simple pendulum of length L is equal to the radius of the earth ‘R’, L = R = 6.4 x 10 6 m, then the time period T = 2π √R/2g; For infinitely long pendulum L > > R near the earth surface, T = 2π × √(R/g) Physical Pendulum. The forces which are acting on the mass are shown in the figure. The pendulum is assembled from a string or a light rod with a weight at one end.Galileo was the first to examine its unique characteristics. Winslow, p. 6. Then the period T … PROCEDURE 1. The experiments also used lead and cork balls. Use the exact values you record for your data to make later calculations. Still using L3, set up the pendulum with an angle larger than 450. For the simple pendulum determine which parameters affect the period (defined as the time for one complete back and forth swing) of the oscillation. First, several assumptions simplified the experiment into an easily modeled system. The aim of the experiment is to test whether light is required for photosynthesis to occur. We found that the pendulum goes slower … Labs for College Physics: Mechanics Worksheet Lab 1-1 Simple Pendulum As you work through the steps in the lab procedure, record your experimental values and the results on this worksheet. But what if our environments become more sophisticated? For a pendulum with starting angle θo = 0.5 radians, make a graph showing the angle of the pendulum at t = 0, 0.1τ, 0.2τ, ..., 1.0τ (every 0.1τ - use the small angle approximation!) T2 = Time as the ball drop = 3.60. The experiment was successful since the acceleration of gravity value obtained was close to the accepted value of 9.806. SHM results whenever a restoring force is proportional to the displacement, a relationship often known as Hooke’s Law when applied to springs. After gaining the results of this experiment, I will be able to plan my main experiment more thoroughly. The formula for the time period of a simple pendulum is given by the equation \(T=2\pi \sqrt{\frac{L}{G}}\) where L is the length of the string and G is the force of gravity. The things with which we concern ourselves in science appear in myriad forms, and with a multitude of attributes. Simple Pendulum.
