  1. Mar 5, 2006 #1
    hi all
    im doing a lab on the atwoods machine basically i ahve calulated gravity as eqaul to 7.09 m/s^2 so i am way off because tis really 9.81. its because of human error when i was using the stop watch.
    i cant rember the formula for figuring out the perecentage of error even tho its really simple lol:rofl:
    its sumthing like 9.81 - 7. 09 then u multply or divive to get ur percentage
