The Surprising Force Behind Newton’s 3rd Law of Motion

Have you ever wondered why objects move the way they do? Newton’s 3rd Law of Motion provides us with a fascinating insight into the forces that govern our world. In this article, we’ll explore the hidden power behind this law and how it affects everything from the tiniest particles to the vastness of space.

Unveiling the Secret: For Every Action, There is an Equal and Opposite Reaction

Newton’s 3rd Law of Motion states that for every action, there is an equal and opposite reaction. This means that whenever an object exerts a force on another object, the second object exerts an equal and opposite force back. It’s like a cosmic game of ping pong, where the forces are always balanced.

Imagine you’re sitting in a chair right now. As you exert a downward force on the chair, the chair pushes back with an equal amount of force, keeping you from sinking through it. This is a perfect example of Newton’s 3rd Law in action.

From Rockets to Skateboards: Newton’s 3rd Law in Everyday Life

Newton’s 3rd Law is not just a concept confined to textbooks. It’s present in our everyday lives, often in ways we don’t even realize. Let’s take a look at some examples:

1. Rockets: When a rocket propels itself forward by expelling gases out of its engines, the force exerted by the gases pushes the rocket in the opposite direction with the same magnitude. This is how rockets achieve liftoff and travel through space.

2. Skateboarding: Ever wondered how skateboarders perform tricks like ollies and kickflips? It’s all thanks to Newton’s 3rd Law. When they stomp on the tail of the skateboard, the board exerts an equal and opposite force on their feet, propelling them into the air.

The Invisible Forces That Shape Our Universe

Newton’s 3rd Law extends far beyond our immediate surroundings. It plays a pivotal role in shaping the entire universe. From the orbits of planets to the formation of galaxies, the law governs the interactions between celestial bodies.

When a planet orbits around the sun, the gravitational force exerted by the planet on the sun is matched by an equal and opposite force exerted by the sun on the planet. This delicate balance allows celestial objects to maintain their orbits and prevents them from colliding with each other.

Unleashing the Power of Newton’s 3rd Law

Understanding Newton’s 3rd Law opens up a world of possibilities. Engineers and scientists harness its power to design and create innovative technologies. For instance, the principles of rocket propulsion, jet engines, and even the humble bicycle all rely on the application of this fundamental law.

By comprehending the equal and opposite nature of forces, we can also predict the outcomes of various interactions. This knowledge enables us to build safer structures, improve transportation systems, and even explore space.


Newton’s 3rd Law of Motion is a fundamental principle that governs the way objects interact with each other. From the everyday scenarios to profound cosmic phenomena, this law offers us a glimpse into the invisible forces that shape our world. By understanding and applying this law, we can unlock new possibilities and push the boundaries of scientific discovery.
