CMaggio Posted October 16, 2012 Share Posted October 16, 2012 This method had a higher percent error due to the attempt to time the exact moment when someone jumps off the ground and lands on the ground using a stop watch can obtain very inaccurate information. The person timing the person in the air will not know the exact moment of when the person jumps up, with different reactions, and when their feet hit the ground. An accurate version of this expriment can be created by using censors to measure the exact time the person is in the air. There could be a censor anywhere on the body where it would be constant, then the other person could set up a seperate censor to measure the person jumping. This censor could be hooked up to a computer or something that would show the exact time. That way, the timer would be more accurate because there wouldnt be another person trying to time the jumper.

marisajorlando Posted October 17, 2012 Share Posted October 17, 2012 When timing a persons jump with a stop watch, there are many things that can effect reslts and create error. When one person jumps in the air not only is it hard to time the starting of the timer perfectly, but the button on the timer also takes time to press down. Even few miliseconds will scue the results. In addition, when the group members have to measure their jump on the wall, each jump will be different so it is very hard to get precise measurements. To make this more precise, we should use a small trampoline with sencors, so that everytime someone jumps on it, it will mark the intervuls of time. This method will decrease any major errors.
