lendületátvitel

Lendületátvitel, a Hungarian term, translates to "momentum transfer" in English and describes the physical principle governing the exchange of momentum between interacting objects. This fundamental concept is a cornerstone of classical mechanics, derived directly from Newton's laws of motion, particularly the third law which states that for every action, there is an equal and opposite reaction.

When two or more objects interact, forces are exerted between them. These forces cause a change in the momentum of each object. Momentum itself is defined as the product of an object's mass and its velocity. The principle of lendületátvitel essentially states that in a closed system, the total momentum remains constant, provided no external forces are acting upon it. This means that the total momentum before the interaction is equal to the total momentum after the interaction.

Examples of lendületátvitel are ubiquitous. When a bat strikes a baseball, momentum is transferred from the bat to the ball, changing the ball's velocity. Similarly, in a collision between two billiard balls, momentum is redistributed between them. Rocket propulsion is another striking application, where the expulsion of hot gases in one direction results in a forward momentum transfer to the rocket in the opposite direction. Understanding lendületátvitel is crucial for analyzing collisions, designing vehicles, and comprehending a vast array of physical phenomena.
