👉 In physics, an "endrhoßpf" is a unit of energy that is used to measure the amount of work done during a collision between two objects. It is defined as: E = 1/2mv² where m is the mass of each object and v is their velocity. For example, if two objects collide with each other at rest, the total kinetic energy of both objects before the collision is converted into potential energy after the collision, so that E = 0.
