The Rules of Movement! 🍎

  **Sir Isaac Newton** was a brilliant scientist who figured out the three fundamental rules that govern how everything moves (or stays still) in the universe. These are the three **Laws of Motion**.

  These laws explain everything from why a soccer ball stops rolling to how rockets launch into space. They all involve **force**, which is a push or a pull.

The Three Laws Summarized 📝

 

1st Law: Inertia

 

An object in motion stays in motion, and an object at rest stays at rest, unless acted upon by an **unbalanced force**.

 

2nd Law: F = ma

 

The **acceleration** of an object depends on its **mass** and the **force** applied to it. More force = more acceleration. More mass = less acceleration for the same force. *$(\text{Force} = \text{Mass} \times \text{Acceleration})$*

 

3rd Law: Action-Reaction

 

For every action, there is an equal and opposite reaction.
