A New Interpretation on the non-Newtonian Properties of Mass

It is well known that the mass of a particle has properties different from Newtonian mechanics. First, it is speed-dependent. Second, it is convertible to energy. These properties are generally believed to be derived from the principle of relativity. A careful examination of the historical records, however, reveals that such a view had some criticisms that could not be ignored. In this work, we explored if the non-Newtonian properties of particle mass could be the results of wave-particle duality. In Newtonian mechanics, the particle is treated as a rigid object. But in the quantum world, we know the particle behaves more like a wave packet. Can such a wave nature account for the deviations from Newtonian mechanics? In this work, we show that this is indeed the case. We developed a wave model which shows that the mass of a particle is speed-dependent and the mass is related to energy. Furthermore, this model can directly explain why particles cannot travel faster than the speed of light. Finally, we proposed that this new model can be tested by experiment.
