Homework Help: Sources of error for lab

Posted by McHelpme on Saturday, September 15, 2007 at 7:39pm.

Hey! So I need help coming up with a source error for this lab I did. We rolled a car down a wooden board and timed the cart rolling down at different distances on the board. So far I have errors dealing with friction, the stopwatches, and the wooden board (kept on falling). I need one more (cant be human error) Have any ideas other than what I have? Thanks a zillion
