4. Calculate the displacement of the spring from its equilibrium position, y = y 1 -y 0 and record in Data Table 1. 5. Convert the total mass from unit of kilogram to Newton and record weight in Data Table 1.
6.Plot a graph of weight vs displacement using the experimental data recorded in Data Table 1.7.Fit the data by a regression line, the slope of which is the spring constant k.Part 2With a mass of 300g on the 50g weight hanger, stretch the spring about 1 cm from the equilibrium position of the system. Release the weight and measure and record the time for ten complete vibrations. In counting the oscillations, count zero at the instant you start the time clock. Repeat this procedure with one vibration amplitude of about 3 cm. Record the time in Data Table 2. Compare to see if you obtain similar result and verify that the period of vibration of a body on a spring is independent of the amplitude.Part 31.With different mass added on the 50g weight hanger, stretch the spring a small distance from its equilibrium position. It is important that the vibration amplitude should be kept in such a way that the mass will be somewhat stretched even at its highest position. Release the weight and measure and record the time for ten complete vibrations. In this procedure, the time measurement should be done at least 3 or 4 times, preferably with each member of a group doing the timing.2.Calculate the average time for ten complete vibrations and further the oscillation period Tand T2for each different mass and record in Data Table 3.3.Plot a graph of m vs T2, fit it with a regression line and the spring constant could be deduced from the slope. Part 4 1. Hang the pendulum at the grove of the small Al rod. 2. Adjust the pendulum length to 10cm, 20cm, 40cm, 60cm, 80cm, and 100cm.
