Simple Harmonic Motion Essay

The pendulum was pulled to about 15 cm from the motion detector. In case of the mass on a spring, the mass was pulled till just a few inches away from the motion detector.

This is then done for all trials. Then, once all five values of k are found, the average is taken by adding all five values of k and dividing by 5. The experimental k average is 0.105894M/s.

Find from the “Starting” and “stopping” locations of where you are going to measure. i.e., I am going to have Charles lay down and I will measure from the bottom of his feet to the top of his head

To begin the experiment, we measured the masses of the two stoppers and the eye bolt used to secure the stoppers that we were using in our apparatus. The mass of the first stopper was 18.8 grams and the mass of the second stopper was 50.5 grams. The mass of the eye bolt was 11.6 grams. The mass of the screw and bolt that secured our hanging mass was given to us as 25 grams. After, we chose six different hanging masses based on stopper mass. We made sure that the hanging mass was always larger than the stopper mass or else we would not be able to get the stopper to spin at a constant velocity. The first three mass ratios we chose was using the stopper with the mass of 18.8 grams and then we used a hanging mass (the mass of the screw and bolt is included) of 65 grams, 85 grams, and 105 grams. This gave the three mass

.To find out what this amount is, you subtract line 5 from line 4, and enter this amount on line 6.

5 x 2 + -6 x 4 + 5 x 8 + -6 x 1= 10 -24 + 40 -6= 20

Loosen the retaining screw and adjust the horizontal arm to the dimple that produce the 2nd largest radius between the spinning mass and the rotating shift. Allow the spinning mass to hang straight down, without being connected to the spring. Position the pointer directly below the tip of spinning mass and secure the pointer to the base. Use the scale located on the base to determine the radius, r, of the pointer from the rotating shaft. Record this value onto Data Sheet A. The experimental uncertainty in r is estimated to be the width of the spinning mass tip – approximately 0.2 cm.

The slope of this graph, calculated using the average rise / run is also 1. As [S2O8-2] is held constant during these trials, the exponent n for [I-] equals one. The k constant can now be calculated.

8. What stretch resulted in the highest contraction force? What happens to the muscle at the highest stretch levels?

Use a protractor to measure 30° from the equilibrium. Release the pendulum at this angle.

The line of best-fit is used to find the gradient, the T2/L value, if straight or linear it shows that the relationship between the two is directly proportional. Using the original equation, you can square both sides and rearrange it to make . Then you can input the gradient value (T2/L) and work out g. , where g equals 10.13 m/s2. This value is close to the

3.375(1 + r)-1 + 3.375 (1 + r)-2 + 3.375 (1 + r)-3 + ...…+ 3.375 (1 + r)-40+100(1 + r)-40 = 95.6

= (89.14 + 83.72 + 82.7 + 86.54 + 93.87 + 88.88 + 92.5 + 90 + 97.5) ÷ 9

Purpose: The purpose of this Physics Lab is to investigate what factors determine the amount of flexion of the cantilever. Hence, the objective is to establish a relationship between the length of a cantilever, which may give some insight into the physics of cantilevers.
