law of action and reaction

• Fundamentales Prinzip der Physik, oft mit dem dritten Newtonschen Gesetz verbunden, wonach auf jede Aktion eine gleich große und entgegengesetzte Reaktion erfolgt. Im weiteren Sinne besagt es, dass jede Ursache eine entsprechende Wirkung hat.

A fundamental principle in physics, often associated with Newton's third law, stating that for every action there is an equal and opposite reaction. In a broader sense, it refers to the idea that every cause has a corresponding effect.

1. Newton's Third LawB2formal

   A fundamental principle of physics stating that for every action (force) there is an equal and opposite reaction.

   Drittes newtonsches Gesetz

   • When you push against a wall, the wall pushes back with an equal force, demonstrating the law of action and reaction.
   • A rocket's engines push exhaust gases downward, and the gases push the rocket upward, following the law of action and reaction.
   • When a swimmer pushes water backward, the water pushes the swimmer forward, which is a practical example of this law.
