To calculate percent error with multiple trials, find the average of the trials, then calculate the percent difference between the average and the accepted value. Divide this difference by the accepted value and multiply by 100 to get the percent error.
Ensure that measurements are taken carefully and consistently, minimize sources of error by controlling variables, use appropriate equipment calibrated regularly, and take multiple trials to calculate an average for more accurate results.
To calculate the percent error, first convert the overshoot in meters to kilometers (10 m = 0.01 km). Then, find the total distance covered by the train (890 km + 0.01 km). Calculate the percent error by finding the difference between the actual and measured distances, dividing by the actual distance, and multiplying by 100. The percent error can be then determined.
p=mv %errror in p= %error in m+%error in v lowest value of m=0 hence %error in velocity=100% k.e=%error in mass=2*%error in velocity K.E=200% similarly K.Eminimun=100% total error in K.E = 100+200 =300 hence error in ke = 300%
Many trials are taken in an experiment as a way to limit experimental error. For example, if you are timing how long it takes a ball to roll down an angled track, as a human being you might release the ball at the wrong time, or push the stop button on the timer early or late. By running multiple trials and averaging the results, these errors should balance themselves out and give a better result.
To calculate the error between two values, subtract the smaller value from the larger value and take the absolute value of the result.

Percent error refers to the percentage difference between a measured value and an accepted value. To calculate the percentage error for density of pennies, the formula is given as: percent error = [(measured value - accepted value) / accepted value] x 100.

Because then you can assess how valid your results are =D
becase it reduces the percent error and it gives a much better idea of what is the best result
Ensure that measurements are taken carefully and consistently, minimize sources of error by controlling variables, use appropriate equipment calibrated regularly, and take multiple trials to calculate an average for more accurate results.
