The mass of the pendulum bob was determined on an electronic scale and its diamter was measured using calipers. The initial height was measured with a meter stick. At the lowest point of its swing, the pendulum bob broke a photogate light beam. The time interval that the light was interrupted was recorded on an electronic timer attached to the photogate.
Use the following data to complete a report.
MAss of pendulum bob = 240.3 g
Diameter of pendulum bob = 3.50 cm
Initial height of pendulum bob = 48.0 cm
Length of pendulum string = 2.14 m
Time interval of photogate light interruption = 11.8 ms
Your report should include the following:
(a) conclusion as to whether or not the pendulum demonstrated the law of conservation of energy
(b) calculations of the efficiency of the pendulum as a mechanical machine
(c) any statements of sources of error
(d) your suggestions for improving the design of the investigation.
Relevant equations[/b]
3. The Attempt at a Solution
Am I supposed to perform this experiement myself, becuase they are giving me all the measurments (therefore am I just doing an analysis) I am not quite sure how to go a outs this since they give me everything
To see if it obeys law of conservation Of energy I was going to see if the initial height matches the final hiring using 9.8m/s and my v ... Is that correct and how do I find efficnecy
