Theorem of Momentum

Every novice driver learns this. The braking distance at 20 km/h is four times as long as at 10 km/h.

It takes four times as much energy to accelerate something to 20 km/h as it does from 0 to 10 km/h. In other words: From 0 to 10 km/h, one unit of energy is needed, and from 10 km/h to 20 km/h, three units of energy are needed. If you were to assume a system traveling at 10 km/h (System B), you would only need one unit of energy to accelerate to 20 km/h. Two units of energy are missing. The law of momentum ensures that all of this is still true. System B loses two units of energy compared to System A (0 km/h). Without the law of momentum, the law of conservation of energy would not be universally valid. More complex laws of nature can be reduced to simpler ones.*
A charged particle moving in an electric field is deflected. However, it can only change its direction if it transfers momentum to another mass.
This raises the question: Does the electric field even exist? The electric field exists, it can be measured, and according to Einstein, it moves at the speed of light. It is to be assumed, however, that the electric field does not exist in itself; it is merely a property of matter. The same could be said of gravity, space, time, and other forces, which are also affected by the law of momentum.

Reminder:
Momentum is defined as mass times velocity. For every action (collision, acceleration, deflection, energy conversion), the sum of the momenta before must equal the sum of the momenta after. This law of nature is called the law of conservation of momentum.

*I still don't believe in a universal formula. In my opinion, the belief in it is based on a simplification by the human mind. Different scientific theories must not logically contradict each other. Therefore, I suspect there are people who believe that these similarities point to a universal formula.
However, the principle of momentum is a kind of universal formula. In an elastic interaction between two massive objects, the smaller object in the center-of-mass system carries with it the greater kinetic energy. This explains why the Earth revolves around the Sun and not vice versa. It also provides a basis for entropy. This also supports the escape of particles from heavy stellar objects.
