But let's go deeper, what is potential energy? Since the very nature of wave-particles is the vibration (nothing is never at rest and there are particles transmitting the "potential energy"), the energy of the whole universe must therefore be kinetic by nature. I think classical mechanics isn't...
But in the end, everything in this universe is movement of particles. Particles are never still, so all energy that there is, should be ultimately tied to the vibrations of particles/waves.
I was trying to think, that there must be total amount of "kinetic energy" in form of general vibrations of particles that remains conserved, just like momentum. But I have no way to calculate and check if that is true so I am stuck with this hypothesis.
I have this problem also, that whenever...
Momentum = mv
I understand that kinetic energy is scalar instead of linear, but shouldn't it still amount the same if billions of molecules/atoms are vibrating at very high speed?
But if momentum is conserved because the total mass and movement amounts to the momentum before and after, why isn't kinetic energy of moving particles in form of heat account for total kinetic energy the same way?
I just don't understand, why heat isn't kinetic energy? Heat is movement of particles. If collision causes molecules to vibrate, isn't the kinetic energy conserved?
Those "Newtons balls" is just theoretical model to illustrate certain equations etc. But in reality there are no "closed circuits", everything affects evertything. Whenever we define any systems, there appears to be leakage of momentum, energy etc.
In case of Newtons balls-device, the balls...
I have trouble understanding, why talk about "systems"? Its not possible to include everything, because the system is bound to have boundaries and it loses momentum unless the whole universe is the "system", in which case momentum is constant like energy.
Well, as far as I understand this classical mechanics, the balls itself do lose their momentum but it stays the same in the "system", but when looking the single ball it does lose momentum. Momentum = v*m, and the velocity of the balls will drop over time because nothing can move forever, so it...
I don't really understand, since momentum is less each moment because if dissipating energy. The balls slow down and eventually stop since they lose momentum, otherwise they would stay forever at the same velocity.<
Also another question I am thinking is, that how can gravity be Newton force...
How can swinging balls conserve momentum? The balls will have less momentum every moment, since energy dissipates? If the momentum was the same in the balls, the balls would never stop?
Yeah, but what is force? If its not transmission of energy? Then how do objects get their "kinetic energy" from getting hit by something etc?
Also, I still don't understand where does falling object get more force to hit the air molecules? The object still has the same gravity force applied to...
When object falls through air and reaches terminal velocity, where does the falling object get its "force that's equal to gravity"? The force applied to the object is still the same that is caused by gravity. Simply, if the object doesn't already push the air with same force the moment it starts...
What else "force" is than energy going somewhere? I am confused. Doesnt the Earth receive some amount of energy? The ground beneath can have some kind of "leave crater"
