comment Does inelastic collision say the ball bounces back to you when thrown at an angle on ground?
Thanks for the answer! However I'm having a lot of trouble to convert differential formulas to code, or even fully understanding them. I don't even remember what that arrow syntax means any more. I understand that's not your fault, but it means I will need some time to process this answer.

I decided to postpone rotation for later, but I'm interested in that too.

It's 2D simulation.

Can you please suggest correct formula then? Such that properly handles deflecting and is 2D aware?

comment Can lasers lift objects?
@Federico Yes indeed. This is the question of "What if we tried more power?"

comment Do gravitational vawes deplete energy even if there's nothing they can affect?
@CuriousOne I was more concerned about the at infinity situation where eventually, nothing can orbit or rotate. That seems to mean that eventually, universe should literally stop moving.

This would fit well on worldbuilding.SE thought.

comment Can you concencrate paralel laser beams?
@fffred The way you discuss this me is making me very uncomfortable. I never said I'm confident about that statement and given I've got an answer showing it's both possible and easy I see it was wrong. However none of your comments helped me know what is specifically wrong with it, I rather feel you're just throwing your "nope!" at me as if I was deemed too stupid to understand any explanation. Speaking of isolated system - second type perpetuum mobile is not isolated system either still laws of thermodynamic apply quite fine.

comment Can you concencrate paralel laser beams?
@fffred I said "it seems like" and I said it's because "the energy on the left side is more spread out than on the right side". Second law implies the energy is to spread out, rather than concentrate.

comment Can a tomato pierce a hole in a steel plate if only the tomato is travelling fast enough?
"Since laser cutters can cut through steel plates, I would assume it could" - you must be kidding. Laser cutters have nothing to do with that, it's not kinetic energy they're based on.

Is there an7ything to back this claim at all? Water cutters are a different case as that's like throwing a million tomatoes, rather than one.
