Can frictional force accelerate a stationary object as it deaccelerate?

If we can design an object with such a surface full of black and white stripe.....
Then it will get more force on one side.

Think ourself.

Yes its possible.

Is our universe loosing energy?

I think yes.
At the boundary of our universe we are radiating lots of energy into nothing, i.e. outside our universe. This radiated energy will never come back.

Tidal energy. What will happen if we keep using tidal energy for very long? Moon will move away or will come close?

Will high Vx will change Vy? Can we change velocity in a direction without applying force in that direction?

I guess Yes.

as very high Vx will increase V, so will the mass be increased, becaz of relativity, so to keep Py constant Vy have to reduce as we know momentum is =M.V.

Can a charge apply force on itself?

I think Yes.

As we know two charges interact using photons. Photos is em wave and travel at speed of light.
But em wave travel aat different speed in different medium.
So we can plan a system such that the em wave will travel through the medium at a speed slower than the speed of light and the charge will travel outside the medium at higher speed. And the charge will interect with its own photon and will feel force.

Is it possible?
