Konstantinos Tsagaris LAB REPORT 1 (the simple pendulum) Research doubtfulness: The point of this experiment was to observe and justify how the time it takes for a pendulum to do an oscillation depends on the length of the rod attribute the tag. Independent uncertain: length of the massless rod Dependent variable: plosive speech sound of a swing avow variables: mass of the trailsleighsleigh, limited pivot, amplitude theory: I endure the period of the oscillation to be relative to the length of the rod. appliance employ: frictionless pivot, massless rod, massive bob, stopwatch, ruler, calculator How I limiting the IV: Since the massless rod, in my case, was a string secure close to the pivot I changed its length by unwrapping it and I thrifty it with the ruler. How I measure the DV: In line of battle to bring on more valid results I me asured the time it took for the bob to oscillate 5 times with the stopwatch. Keeping the controlled variables constant: By doing some calculations and finding the position from which I would let the bob start to swing I measured its distance from the crossways of the pivot by using the ruler in rig to keep a constant amplitude. Also I employ the same ruler and stopwatch in every info collection so that I wouldnt have divergent uncertainties.

Range of the IV: 40cm,60cm,80cm,100cm,120cm Times of DV measurement: 5 measurements for each value of the IV Raw data: Time interpreted for 5 oscillations (s) +0.1s (because of the decimal limit ! of the stopwatch I used)| continuance (cm)+0.1cm| beginning(a) trial| 2nd trial| 3rd trial| stern trial| 5th trial| All trials| 6.4| 6.4| 6.3| 6.3| 6.4| 40.0| 7.7| 7.8| 7.7| 7.8| 7.8| 60.1| 9.1| 9.1| 9.1| 9.0| 9.0| 81.7| 10.1| 9.7| 10.2| 9.8| 10.1| 100.2| 10.9| 11.1| 11.0| 10.9| 10.9| 120.0 (+0.5)| (*turn to future(a) summon to see the sketched graph) Conclusion:...If you want to get a effective essay, order it on our website: OrderEssay.net
