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

It is hard for us to know how the lab was accomplished. Was the ramp straight, or bowed?

  It was straight. It was a straight wooden board. We held up the wooden board with different objects, to increase the angle of inclination/height, and then dropped the cart down the wooden board. (Does that help)

What about the measurement of the inclination angle?
