Question

I'm rather confused as to how I should go about calculatingabsolute uncertainty. What is the formula?
For example, if I'm finding the momentum (wheremomentum=mass*velocity) and the mass is 0.0215 +/- 0.0002 kg and the velocity is 4.282 +/-0.302 m/s, what is the absolute uncertainty of the momentum?
...will rate lifesaver immediately! What is the formula?

Explanation / Answer

                 Heisenberg Uncertainty principle = x p  h/2                 where x is measurement of position of the particle                              pis linear momentum                                  p= mu where m is maass of the object & u is velocity                       According to de Brogile wavelength is given by = h/p =h/mu
