  "textContent": "Impulse is tricky. Excuse me, it has been 9 years now that I last programmed physics, I am relearning many things, but impulse is Ns (FΔt just like momentum), while force is N (F). So I suppose the timestep (accuracy) of the physics is applicable in prePhysicsTick(PhysicsSpace space, float timeStep). However I haven’t used impulses yet and my problem was with applying forces.",
