1Lab Report: Acceleration Due to Free FallAnalysisThe first graph displays an exponential curve that is derived from the location of the bob in respect to time. Like speed, the slope will have certain characteristics. For instance, a straight line will be obtained if the velocity remains constant, as this will cause the slope to remain constant as well. Graph 2 shows a curved line because the slope changes as a function of changing velocity. In a positive-velocity situation, the slope will be positive. We can still make a mistake if we use this method to calculate "g" though.Experimental errors can be caused by many different things. It is possible that human error will cause the video recording to begin after the bulk drops have already occurred. The fact that you began filming before realizing the bob had dropped might have been an oversight. Attempting again after a while might help lower the margin of error that comes with this kind of slip-up. When using a measuring tape to determine how far away the bob is, another potential source of mistake is parallax. Perhaps the bob's rapid speed was a factor in the slip-up as well. As it climbs, it poses a risk of reducing the amount of time the camera can record. Because of this, the bob could look fuzzy. This would allow us to make an educated judgment as to where the center of the clouded image lies. When you measure the bob from different angles, it will throw off your estimations if it is unclear. h (m)t (S)v(m/s2)v212average0.100.0370.0370.0370.200.0270.0260.027
