Physics help T.t
can anyone tell me experimental errors of the walking lab? I can't think of any.
the walking lab is pretty much a lab were people walk and are timed. (this is to see there average velocity and if humans can walk at a constant velocity)

Ok so far I have for experimental error
Our answer can only be accurate to a certain degree because the stop watches only go to milliseconds so our answers have to be rounded off the milliseconds.
and Since humans can't walk in a straight line, the calculations are probably a bit off because the distance traveled isn't accurate?
I need 1 more but I don't think those two count for experimental errors o-O? But still thanks alot guys I can still use them for human errors.
Hmm..besides the ones already posted, you can say that we don't really walk in a straight line, so it would mess up the distance traveled.
You could say your answer is only certain to a degree of measurement and not ever being exact. Ex. You measure in centimeters but you have to guess the millimeters.

If the distances aren't fixed in advance, you can also state the measuring errors you could get, as you would get relatively crude measurements (I remember having to use a metre stick, no tape measure lol).
Can't think of anything else, but try to find of things that you experimentally observe that could possibly have error.[/quote]
aha thanks but my teacher measured all of them on a string and laid that down the hall, could one of them be that since its string, it has a propertly in folding in on its self so the measurements wont be exact.

I think that's all what you need since they are the most common ones.
