Hey guys, I was wondering how to do a percentage error for this lab experiment I did. It was the ball down the ramp. My teacher told me to find it I needed to do error/accepted value, so we worked out the accepted value together, but there wasn't enough time to find the error. How would I go and find the error? All I have is my data table with the final velocity of the ball rolling down 2,3, and 4 meters, would i use the average of the velocity/accepted value?
