According to Heisenberg's uncertainty principle, changing the uncertainty in a particle's position through measurement changes the particle's momentum. Newton's second law states that a changing momentum is due to a force on the particle. Therefore, changing the uncertainty in a particle's position through measurement changes the particle's momentum and generates a force on the particle. Understanding the consequences of measurements creating forces requires a conceptual derivation using thermodynamics and relativity concepts.Motion is not absolute; a quantum particle requires a second particle to provide a relative position and momentum. A measurement generates a force and creates a non-inertial reference frame. Without a measurement, velocity, momentum, and position are undefined. The particle occupies every possible allowed state simultaneously until a measurement defines the observables, increases entropy, and collapses the wavefunction.Many quantum mechanics interpretations use the complex wavefunction to obfuscate the underlying mechanics. Interpretations describe observable particle properties as consequences of ideas which science cannot falsify. It is impossible to measure imaginary numbers experimentally. The Heisenberg uncertainty principle eliminates the need for the Born rule, as it already contains the squared wavefunctions. Applying oscillating uncertainties provides a logical mechanism for forces and extends into the spherical harmonics of atomic physics.
