The Collision a phenomenon in which two moving objects touch each other exerts a strong force (impact) only for a short period. Before and after a collision, the sum of the motion and angular momentum of the two objects does not change, but the kinetic energy is partially converted to thermal energy. The ideal case where the kinetic energy is conserved is called a fully elastic collision. If an object moves in relation to time relative to other objects, this state of the object is called motion. In general terms, the meaning of motion - change in the position of an object is called motion.
