law of action and reaction

• Фундаментальный принцип в физике, часто связанный с третьим законом Ньютона, гласящий, что на каждое действие существует равное и противоположное противодействие. В более широком смысле это относится к идее, что у каждой причины есть соответствующее следствие.

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.

   Третий закон Ньютона

   • 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.
