# Question about dividing uncertainties? watch

1. so. If I have a set of times and a set of distances, and I want to calculate the uncertainty of the velocities,

how do I do this?

My 'formula' looks like this

v=dist.+-0.005/time+-0.001

What would the uncertainty for the velocity be?

thank you.
2. Find the % uncertainty in both distance and time, then add the % uncertainties.
This gives the % uncertainty in the final value so convert it back to an actual uncertainty.

BTW.
If you have a series of values it is normal to either draw a graph (if that is relevant) and find the gradient; or find the average of the values and use that.
