Which law states that for every action there is an equal and opposite reaction?

The law that states for every action there is an equal and opposite reaction is Newton's Third Law of Motion. This principle highlights the interaction between two objects, indicating that when one object exerts a force on a second object, the second object exerts a force of equal magnitude but in the opposite direction on the first object. This relationship is fundamental in understanding how forces work in dynamics and is crucial in various mechanical applications, including gas turbine systems.

Understanding this law is essential for gas turbine technicians, as it applies to the forces at play within turbine engines, where the combustion gases push against turbine blades, leading to rotation and thrust. This principle underscores the mechanics of propulsion and energy conversion within the system, illustrating why components must be designed to withstand these forces effectively.
