frastødningskraft
Frastødningskraft is a term used primarily in Scandinavian languages to describe a repulsive force, that is, a force which acts to separate two objects rather than attract them. In physics it is the natural counterpart to the attractive force described by Newton’s law of gravitation or, in electromagnetism, the electric repulsion between like charges. The concept appears also in biological contexts, where it can refer to deterrent signals or physical reactions that keep organisms at an advantageous distance.
In classical mechanics the quantity is calculated by similar formulas to those used for attraction but with
Frastødningskraft is used in engineering to design anti‑collision systems, in robotics for obstacle avoidance, and in
