Add 100g weight to the hanger. Record y1 at the bottom of spring3.Add more weight to the hanger4.Calculate displacement: y = y1 – y05.Plot graphPart 2:With mass 300g on the hanger, stretch the spring from the equilibrium position 1cm. Release the weight and measure and record the time for 20 vibrations. Repeat the procedure with a longer amplitude of 3cm.Part 3:1.With different mass added to the hanger, stretch the spring from its equilibrium position. Release the weight and measure and record the time for 20 vibrations.2.Calculate the average time for 20 vibrations and further the oscillation period T and T2 for each different mass3.Plot graphPart 4:1.Hang the pendulum at groove of small Aluminum rod2.Adjust length to 10cm, 20, 40, 60, 80, and 100cm. For each, displace the pendulum a small angle off the vertical direction and release it, measure time for 20 oscillations. Take the average to find T and then find T2.3.Plot graph L vs T2. Find g from the slope and compare with standard 9.8 valueResults/Calculations:Table 1:Mass of total weight m (kg)Weight of total mass w(N=mg)Position y1(m)Displacement y=y1-y0(m)0.05 + 0.101.47660.0130.05 + 0.202.4562.40.0490.05 + 0.303.4358.10.0920.05 + 0.404.41540.1330.05 + 0.505.3949.90.174Table 2:Mass of total weight m (kg)Time for 20 cycles for 1cm
