error. Do not quote human error as a source of experimental error. Systematic error air resistance systematic error is an error inherent in the experimental set up which causes the results to be skewed in the same direction every time, i.e., types of error in experiments always too large or always too small. One example of systematic error would be trying to measure the fall time of a ping pong ball to determine the acceleration due to gravity. Air resistance would systematically reduce

the measured acceleration, producing a systematic error. Some systematic errors can be easily corrected. For example, if a balance reads 0.25 g when there is no mass on it, this would introduce a systematic error to each mass measurementthey would all be too large by 0.25 g. This can be corrected by zeroing the balance. Other systematic errors can only be eliminated by using a different experimental setup. Most of the simple experiments you do

will have some systematic error. All experiments have random error, which occurs because no measurement can be made with infinite precision. Random errors will cause a series of measurements to be sometimes too large and sometimes too small. An example of random error could be when making timings with a stopwatch. Sometimes you may stop the watch too soon, sometimes too late. Either case introduces random error in your measurements. (Note that when a human is involved in the actual measurement process, he/she can introduce valid experimental error that is not within the definition of human error. Your finite reaction time is not a mistake; it is a limitation of one part of the experimental process, the human making the measurement.) Random error can be reduced by averaging several measurements. ERROR ANALYSIS One way to analyze experimental error is with a % error calculation. The % error is useful when you have a single experimental result that you wish to compare with a standard value, or when you have two experimental values obtained by different means that you wish to compare. (In the latter case it is often called % difference since there is no standard to compare to.) The % error is calculated according to the following formula. In the formula, 1 "expt. #" is your experimen

CONCLUSION With all the sustained information I have gathered, I therefore conclude that velocity and acceleration are bothdependentontimeanddisplacement.Meaning,the velocity and acceleration changes as the time and displacement also changes. Hence, time and displacement are directly proportional to another becauseofitslinearrelationship. direction are defined at its time interval.
