Hi, I have a basic physics engine and i wonder in what conditions i can assume that the particle (the body) is resting. By "resting", I mean extracting the particle from simulation as soon as a force is applied to it. For example i apply a force to the partice and the world simulates its movement by calculating the gravity's force on it. So how can i assume that my particle's movement is finished. The velocity's of my particle never get's zero as the gravity affects it even it collides with the ground. Thanks for your answers,

If the particle's velocity has been very small for a number updates/ticks/frames then you can call it resting and remove it from updates until a large enough force is exerted on it.
