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?

how would that be an error?

when doing a chromotography lab what are the sorces of error

Hello! It sounds like you're looking for another potential source of error for your lab. Based on your description, here's a suggestion:

One possible source of error could be the unevenness or irregularities on the wooden board. If the surface of the board is not perfectly smooth or if there are any bumps, grooves, or imperfections, it could cause the cart to experience varying levels of resistance and affect the timing measurements. This inconsistency in the surface could introduce an additional unknown factor that may affect the accuracy of your results.

To mitigate this potential error, you could consider using a different type of board with a more consistent surface, such as a metal or plastic surface. Alternatively, you could perform multiple trials at each distance and calculate the average values to reduce the impact of any irregularities on the board.

Remember, the purpose of identifying potential sources of error is to acknowledge the limitations of your experiment and discuss how they may have influenced your results. It's great that you're considering these aspects in your analysis!
