Extract of sample "Conservation of momentum"

Conservation of Momentum. Analysis of data. Part Average height of the center of gravity rise is given by; Average = total quantity /number of quantitiesh = 84.7cm or 0.847mVelocity v would be given as;V= √2gh = √(2x 9.8x 0.847) = 4.074m/sV= (M +m /m) x 4.074V=(0.1943+0.0577/0.0577)x 4.074 = 17.79m/sPart 2.The average range is given by the total quantity / number of quantities. This would be given as; X = (252.5+259.8+264.5+ 263.4+ 275.5)/5 = 263.14cm or 2.631m According to equation 9V=x/t=x/√(2y/g) = x√(g/2y) = 2.631√(9.8/2x0.847) = 6.328m/s The muzzle velocity calculated by equation 9 is almost half that calculated by equation 6.

This is due to the errors during the experiment. In this experiment, obtained values were not the exact theoretical values due to the errors that were made during the experiment. Some of these errors were made while taking readings (parallax), due to faultiness in the stopwatch, air resistance, and due to wrong calculation or miscalculation in taking values. It is recommended that for experimental errors to be reduced the following steps should be followed. During the experiment one should ensure that at least three readings for a particular step are taken then an average of the reading obtained so as to minimize the errors of parallax.

The experiment needs to be done at least twice to confirm the recorded values and minimize the errors. The stop watch and all the apparatus used for the experiment needs to be observed before the beggining of the experiment to ascertain their efficiency. The experiment could also be done in an area with vacuum conditions in order to minimize the interferences in obtaining the readings due to air resistance. The two values for V obtain in part 1 and part 2 are not as close as they are expected.

This is so due to the errors during the experiment. Without errors, the two values of velocity should be the same. Reanalyzation of the tale values using the largest h fails to make any significant change in the final results of v (Susan 10). The fact is that the two values fail to be as close as they are expected to be. However repeating the entire experiment while avoiding the experimental errors may give out values that are close to the theoretical values.Work cited.Susan, A. Conservation of momentum.
