    you are on a bicycle in an isolated system earth bycicle and you make a circle of decreasing radius

    if you increase speed cons of energy will be false if you keep constant speed cons of momentum will be false, unless...

    another kid at another part of earth goes maybe in skates making a circle of increasing raidus

    this has puzeld me long, the bicycle making circles of varying radius and this is the only answer that keeps true the principles ive found

    on this way artificial gravity or antig could not break the physics laws if somebody else in the universe used it the opposite way

    You are overlooking the force between the bicycle and the earth. That is the source of the change in momentum. Since momentum is a vector quantity, the momentum is constantly changing as the direction of the bicycle changes. The force that creates the required acceleration is the frictional force between the bicycle and the ground.

    but what does it make it different a bycilcle fixated to earth by a frictional force than united by a cable

    If an object were tethered by a cable, and if the cable were retracted the speed would increase so as to conserve angular momentum. The kinetic energy wouod increase, and the increase would equal the work done in pulling on the cable to retract it.

    thanks for your time but what i dont understand:

    doesnt cons of mom state that m*v*r is constant in an isolated system?

    in the system earth bycicle of varying radius this seems false as i see it, instead is not in the case of a ball and cable

    the earth has a momentum too.
