Pendulum Lab

Pendulum Lab Hypothesis: To calculate the time it takes the pendulum to swing dorsum and forwards one time. Materials: String Small Weight cadence Tape clock or stopwatch Diagram: turn: 1. Start with a firearm of delineate 120 cm long: 2.Tie the heaviness onto the string, fasten the string to something which will resign it to swing freely, conform the string length so that it is c cm long. 3. hale the weight back a few inches, let it go and time how long it takes to make 30 swings back and forth. 4. apportion the time by 30 in order to experience the time for 1 swing. 5.Calculate the accepted abide by for T by using the formula below. (remember l should be in meters) 6.Shorten the string by to a length of 90 cm and repeat stairs 2-5 7. On graph paper, truss a graph of T2 vs l. This graph should be a sincere line (why?), so draw a line of twinge fit. 8. Calculate your average % erroneous belief, and explai n it in your conclusion. It should be rattling low for this lab! Also, does your % error get worsen and worse as the lab progresses? Why? %Error= Calculated- observational X 100 Calculated 9. In your conclusion, answer the (why?) in procedure steps 7 & 8 Results: Length of string (cm) quantify for 15 swings (s) Time for 1 swing (s) veritable value of T (s) % error calculated (%)T2 (your value from towboat 3) 10030.92.062.003.04.00 9028.11.871.901.63.61 8026.31.751.802.73.24 7025.31.691.680.62.82 6024.01.601.553.22.40 5022.11.471.423.52.01 4019.21.281.270.81.61 3016.51.101.100.01.21 2013.50.900.891.10.79 109.60.640.640.00.41If you want to get a full essay, order it on our website: OrderCustomPaper.com
