Practice: To what uncertainty (in m) can the position of a baseball traveling at 51.0 m/s be measured if the uncertainty of its speed is 0.12%? The mass of the baseball is 150 g.
Heisenberg's Uncertainty Principle tries to explain the potential duality of an electron behaving as either a particle or wave.
Concept #1: Heisenberg Uncertainty Principle
Concept #2: Heisenberg Uncertainty Principle Formula
Example #1: Calculate the uncertainty in momentum of a neutron moving at 6.00 x 107 m/s. The mass of a neutron is 1.67510 x 10-27 kg.
Practice: To what uncertainty (in m) can the position of a baseball traveling at 51.0 m/s be measured if the uncertainty of its speed is 0.12%? The mass of the baseball is 150 g.
Practice: An electron with a mass of 9.11 x 10-31 kg has an uncertainty in its position of 630 pm. What is the uncertainty in its velocity?
Practice: A proton with a mass of 1.67 x 10-27 kg traveling at 4.7 x 105 m/s has an uncertainty in its velocity of 1.77 x 105 m/s. Determine its uncertainty in position.
