Newton's 3rd law is the one of the most fundamental laws of physics. Newton's 3rd law of motion states that "for every action (force), there is an equal and opposite reaction." This means that when two objects interact, they exert equal and opposite forces on each other. These forces are equal in magnitude but opposite in direction. In this article we will discuss about the Newton's 3rd law examples in real life.
Examples of Newton's third law in examples in real life:
- Walking: When we walk, we push against the ground with our foot. The ground pushes back on we with an equal and opposite force, which propels we forward.
- Firing a gun: When we fire a gun, the bullet is propelled forward by the explosion of gunpowder in the gun barrel. The explosion also exerts an equal and opposite force on the gun, which causes it to recoil backward.
- Swimming: When we swim, we push against the water with our arms and legs. The water pushes back on we with an equal and opposite force, which propels we forward.
- Playing tennis: When we hit a tennis ball, we apply a force to the ball with our racket. The ball applies an equal and opposite force to our racket, which causes we to recoil backward.
- Taking off in a plane: When a plane takes off, the engines apply a force to the air, which propels the plane forward. The air also applies an equal and opposite force to the engines, which causes the plane to push down on the runway.
Applications of Newton's Third Law
Newton's third law has many applications in the real world. For example, it is used in the design of rockets, airplanes, and other vehicles. It is also used in the design of safety equipment, such as seat belts and airbags.
In the field of engineering, Newton's third law is used to calculate the forces that act on objects. This information can be used to design objects that are safe and efficient.
In the field of sports, Newton's third law is used to understand how athletes move and how they can improve their performance. For example, swimmers use Newton's third law to propel themselves through the water, and tennis players use it to hit the ball harder.
Newton's third law is a fundamental law of physics that has many applications in the real world. It is used in the design of objects, the calculation of forces, and the understanding of sports. This law is essential for understanding how the world works around us.

In theory, Newton's third law cannot be broken. However, in practice, it can be difficult to measure the forces involved in some interactions, so it may appear that Newton's third law is not being followed.
