## These thoughts can be used for a rolling body.

The diagram has shown a rolling disk which contains n sectors with mass m. This (centre mass) CM disk has a translation velocity V. The red sector has linear velocity zero. Base on previous explanations, only n-1 sector on the rolling disk has velocity more then zero. These moving sectors transfer linear momentum dP to the surface with mass M+m per time frame dt.
If use classical model: The disk with linear velocity V transfer momentum to the surface. The total velocity on the end of action is:

V1=((n*m)/(n*m+M))*V

If discount the red sector with zero linear velocity: The total velocity on the end of action is:
V1'=(((n-1)*m)/((n-1)*m+M+m))*V.

The velocity difference between these two models is:
V1-V1'=m/(n*m+M)*V

If sectors geometrical size strives to zero, then sectors mass strive to zero also. For velocity difference equation, it gives a zero result.
V1-V1'=0.

At a math point of view with a very small sector with zero linear velocity the surface takes equation
V1=((n*m)/(n*m+M))*V.

However, the physical elements have its own geometrical size and end up velocity for this action is:

V1'=(((n-1)*m)/((n-1)*m+M+m))*V

Velocity difference is:
V1-V1'=m/(n*m+M)*V

# A rolling disk on a straight line surface.

The diagram has shown a rolling disk on straight line surface. This movement has rolling and static frictions. This disk contains n sectors with mass m. The (centre mass) CM disk has an initial translation velocity V. The red sector has linear velocity zero. Base on previous explanations, only n-1 sector on the rolling disk has velocity more then zero. These moving sectors transfer linear momentum dP to the surface with mass M+m per time frame dt.

If use classical model: The disk with linear velocity V transfer momentum to the surface. The total velocity on the end of action is:

(equation 1)

If discount the red sector with zero linear velocity: The total velocity on the end of action is:

(equation 2)

The velocity difference between these two models is:

(equation 3)

If sectors geometrical size strives to zero, then sectors mass strive to zero also. For these velocity difference equation, it gives a zero result.

(equation 4)

However, the physical elements have its own geometrical size and end up velocity may be count by (equation 2)

Velocity difference between classical and this modern models is:
(equastion 3)

For this model, à repulsion and à collision comes on different planes.

The vertical plane doesn't have any contacts with the rolling body.
Otherwise the horizontal plane always has a physical contact with rolling body.

From vertical plane point of view, all elements of rolling body have a movement.
If calculate a rolling body translation momentum with respect to vertical plane then all elements of rolling body must be included.

Otherwise if look on horizontal plane, one element of rolling body stays on the surface all the time.If calculate a rolling body translation momentum with respect to horizontal plane then one element of rolling body must be included to the mass of horizontal plane.

"Follow by law of momentum conservation
V0x(mx(n-1))=V1x(all mass)
If discount one element from the ring then and average speed for (n-1) elements is changing.
The rest or ring elements have average velocity is V'0=(n/(n-1))xV0!"

This is absolutely correct. The momentum is conserve. The average velocity is changing.
P=const=mV=mVo=((n-1)m)x(n/(n-1))Vo. Just one little obstacle this model has. One ring's element stays on the ground with velocity zero.
To solve this problem let reverse frame of reference for this model. The platform moves horizontally with mass M and velocity V. The ring with mass n*m stays and does rotation movement.
For vertical plane (a wall) the platform has a translation momentum P=MV. However, the translation momentum for horizontal plane (the platform surface) counts ring's element, which is joining to the surface with velocity V. In this case the translation momentum is P=(M+m)V. The average velocity is equal to V.
How the momentum can be different for these planes? Answer is horizontal and vertical planes have a different frame of reference. To reach same momentum P=MV. The frame reference center should move with velocity V/n.
WAIT A SECOND!
Are these vertical and horizontal frames of references move relatively to each other?
THIS IS THE ONE.
If action starts from zero velocity on one frame of reference and this action finish with zero velocity for another frame of reference then relativity to the first frame of reference the system will continue to move on the end of action!

The momentum is conserve. The frame of reference is changing. This frame of reference exchange gives the system ability to move.

## A few philosophy thinks.

Collisions may be classified in two groups. Explicit and implicit.

1. Explicit collisions  happens between objects which conducts a simple movements relativity to each other.
For example. A collision between rolling body and wall on the surface. Law of momentum conservation is working.

2. Implicit collisions  happens between objects which conducts a complicate movements relativity to each other.
For example. A collision between a rolling body and a surface (It's kind of weird thing)
This it may happen in 2 cases.
a. Between these objects distortions. Rolling friction.
b. These objects may have shared points to each other during movement action. Coupling through construction elements.
For ideal model the rolling body is conducting rotation with translation movement without any collisions on straight line surface.  The rolling body with complicated movement has a parallel tangential line to the surface.
If use same frame of reference for implicit and explicit collisions the momentum will have a different value.

To avoid this law of momentum conservation problem, the model can implement two possibilities.
a. The model should transform own frame of reference.
If a platform (the surface) is a center of frame of reference then the calculated average velocity of rolling ring is higher than rolling ring's center mass velocity.
If reverse this frame of reference and put rolling ring into center then the platform velocity should be reduced for calculations. From the other word this frame of reference should base on law of momentum conservation. Base on this frame of reference momentum measurement other parameters (like velocity) should be readjusted.
b. The model should include a dark matter.
This dark matter with own mass gives ability to law of momentum conservation works without frame of reference replacement.
For rolling ring model can happening two things. The dark matter may reduce the platform mass or be between objects to compensate extra momentum.

=====================================================================
Are cosmology theories having a same problem?
Is new frame of reference with law of momentum conservation core can eliminate this problem?

Let imagine observer and two objects (A and B). One object A with simple movement can move only into one plane. The observer in own frame of reference sees only this plane also.
Another object B with complicated movement can move in two planes and observer can see only one of these planes.
The object A has position without movement for observer. The object B has a movement. The object B has component velocity for each plane. However, observer can see only one component velocity of objects B . The object A takes momentum from object B after collision and objects A velocity may be higher than inspected.
a. The observer can assume the object A has a huge mass. Or if observer knows the object B mass then he can assume include dark matter for collision process.
b. If frame of reference base on law of momentum conservation then using all know parameters easy to calculate another plane velocity component of object B which is invisible for observer. This velocity component for observer has imaginary character. From the other words, the frame of reference use law of momentum conservation to readjust another object parameters.

A few words about movement without external forces. The object can rotate on own center mass without external forces. However, if alternate simple and complicated movement on object collisions then for observer frame of references it may possible exchange rotation to translation movement.
Everything Is Relative.

This is a good example is shown transfer between angular and linear momentums.
Unfortunately the simulator does not allow giving different angular velocities for squares.
Anyway, on this model easy to understand these squares with different angular velocities will take a different linear velocities on the end of action.
Base on my theory about frame of reference conversion for complicated movement, the law of momentum conservation works, however for correct calculation need use imaginary part of velocity.

The momentum is conserve. The frame of reference is changing. This frame of reference exchange gives the system ability to move.

Another good example:
Let's repulse a long cylinder inside Isolated System. The repulse should hit the cylinder away from object center mass. This hit energy splits for two object movements. This cylinder starts rotation with translation movement. The Isolated System starts move to opposite cylinder translation movement direction. During this object movement let transform this cylinder to a sphere. This sphere is rotating faster than cylinder because this object moment of inertia less than cylinder moment of inertia. However this rotation does not make any sense for translation momentum transfer. The sphere translation momentum is equal to cylinder translation momentum. However from cylinder repulse action the system takes higher translation momentum than sphere has. The sphere translation momentum won't be enough to stop the Isolated System.

This is a good example is shown transfer between angular and linear momentums. Unfortunately the simulator does not allow giving different angular velocities for squares.
Anyway, on this model easy to understand these squares with different angular velocities will take a different linear velocities on the end of action.
Base on my theory about frame of reference conversion for complicated movement, the law of momentum conservation works, however for correct calculation need use imaginary part of velocity.
The momentum is conserve. The frame of reference is changing. This frame of reference exchange gives the system ability to move.

Let's solve simple problem.
Given a long thin cylinder with length L, radius R and mass M.
Case 1.
This cylinder takes momentum P into his center mass.
Case 2.
This cylinder takes momentum P on a some distance from his center mass.
The cylinder start rotation with translation movement.

How many times the translation velocity for case 2 is lower than translation velocity for case 1?
======================================================================

If calculate this problem using classical mechanics laws, the linear momentum should be conserve. However, these cases take different energies. The cylinder with translation and rotation movements will take two parts (translation and rotation) of energies. The cylinder with translation takes only one( translation) part. These translation kinetic energy parts should be equal.
Where this rotation kinetic energy come from? From nowhere? What about angular momentum? How it starts rotating if all momentum transfers to translation part?

If assume for case 2 the incoming momentum vector dividing for two parts initially then it will explain everything. The first part  translation momentum gives ability the cylinder moves. The second part  angular momentum gives ability the cylinder rotates. The sum of these parts kinetic energies is equal to full translation kinetic energy from case1. The case 2 cylinder translation velocity lower than case 1 translation cylinder velocity.
The equation translation velocity is:

Et - kinetic energy translation part
Er - kinetic energy rotation part

Let's make a simple experiment with pencil.
Case 1: Let's hit the pencil on his middle  The pencil fly away on a long distance.
Case 2: Let's hit the pencil on his edge  The pencil starts rotation and fly away not so far.
The classical mechanics solution says  For both cases the pencil should fly away on a long distance with same high translation velocity. No matter how fast it is rotating.

Is it really true? I don't see this result.
