WebJan 9, 2016 · So in this model, momentum is mysteriously acquired instantly. In reality, the two objects interact via the electromagnetic force, where force is gradually applied over time. We get the change in momentum by adding up the force at each point times the time it acted. Hope this helped! WebWell, you can conclude that something is wrong by the following logic: momentum is an observable, which means its allowed values must be things that you could read off a measuring device (assuming you had one that measures momentum). These are necessarily real values, and since the expectation value is some linear combination of …

Can momentum never be zero in quantum mechanics?

WebFeb 5, 2024 · For two objects made of regular matter the force that causes momentum transfer is simply the electric repulsion of the electrons of the atoms on the surface of the … WebFeb 6, 2024 · Momentum creates motivation. Motivation creates opportunity and opportunity creates results. That is how it works and that is why every entrepreneur needs to learn to create momentum in their business. Another great way to keep your momentum going is by attending networking and industry events. moly groves

Webif you want to change the momentum of an object, you have to apply a force. OK?? But if you apply that force for a long time then the momentum will change more. and the effect of the force AND the time the force is applied, is the impulse of the force. so the change in … Momentum is a vector quantity, and therefore we need to use vector addition … So, in order to conserve momentum for this collision, and almost all collisions should … Then divide that x momentum by cos(40) to get the total momentum (x and y) after … WebJul 22, 2024 · It is easy to show that in calculating momentum the velocity vector of the center of mass v C M is grouped outside of the expression. p = ∑ i m i v i = ( ∑ i m i) v C M = m v C M So in the reference frame where v C M = 0, by definition momentum, will also be p = 0.
