Let us consider a spring that is fixed at one end.
These movements of pendulums are called oscillations, which show simple harmonic motion. It swings to and fro about its mean position where the string and the bob undergo the motion. A pendulum undergoes simple harmonic motion. Write a description of the procedure you followed and the data you collected to answer this question.The motion of an object that moves to and fro about a mean position along a straight line is called simple harmonic motion. Using Pendulum Lab investigate this question.Please write down a prediction with a reason for question E.Write a description of the procedure you followed and the data you collected to answer this question.Ĭ) Does the period of motion depend on the Length? Use the PhET simulation Pendulum Lab to investigate this question.Please write down a prediction with a reason for question D.Use the percent error to compare your experimentally determined value of g to the accepted value.ī) Does the period of the motion depend on the mass?.Plot the data to yield a straight line, and then use the slope to determine g.Record the lengths and the corresponding periods in a table. Use the distance from the point of support to the center of the mass as the length. Experimentally determine the periods of five simple pendulums, each with a different length, but the same mass.Taking note of the initial amplitude (remember for SHM motion q ≤ 15 o), pull the mass to one side, release it, and determine the period of its motion.Attach one end of a string to the hook and hang a mass at the other end near the floor.Materials and equipment: masses, string, stopwatch or other type of timer.Ī) Finding the acceleration due to gravity, g if the displacement of the mass m from the equilibrium position is small, q ≤ 15 o.The motion of a pendulum can be treated as simple harmonic if: STEP 4: Now generate the graph, and use its slope to determine k. What are the slope and y-intercept of the resulting line? STEP 3: Using the equation relating period, mass and the spring constant, plot T 2 on the vertical axis and m on the horizontal axis. Record the mass and the corresponding period in a table. Experimentally determine the periods of motion for six masses 50g, 100g, 150g, 200g, 250g and 300g.Please write down a prediction with a reason for question B.Theoretically (according to the equations), does the period of the motion depend on the amplitude? Support your answer.Does your data indicate that the period of motion depends on the amplitude? Support your answer.Record the amplitudes and the periods in a table. Repeat this procedure for five additional amplitudes.How is the amplitude defined for this motion?.Describe how you used this data to determine the period. Use the motion data to determine the period of the motion.Release the mass and use the motion detector to record the motion.Pull the mass below the spring/mass equilibrium position.This will be your spring/mass equilibrium position. Measure the position of the end of the spring relative to the floor or table top.From the lose end of the spring hang a 50g weight hanger with a 50g mass for a total of 100g.Suspend the spring from the support rod.Please write down a prediction with a reason for question A.A) Does the period of the motion depend on the amplitude?
