An object is moving along a straight line, and the uncertainty in its position is 1.90 m. Required:
Find the minimum uncertainty in the momentum of the object. Find the minimum uncertainty in the object's velocity, assuming that the object is (b) a golf ball (mass=0.045 kg) and (c) an electron.

Explanation:

= Uncertainty in position = 1.9 m

= Uncertainty in momentum

h = Planck's constant =

m = Mass of object

From Heisenberg's uncertainty principle we know

The minimum uncertainty in the momentum of the object is

Golf ball minimum uncertainty in the momentum of the object

Uncertainty in velocity is given by

The minimum uncertainty in the object's velocity is

Electron

The minimum uncertainty in the object's velocity is .
