Newtonian mechanics

Newtonian mechanics is like playing with toys. Imagine you have a ball, and you throw it up in the air. The ball goes up, but then it comes back down to the ground. This is because of something called gravity. It pulls the ball back down to the ground.

Now, imagine that you have two balls. You throw one ball towards the other ball. When they meet, they bounce off each other. This is called a collision. Newtonian mechanics is about how objects move and collide with each other. It helps us understand why things move the way they do and what happens when they crash into each other.

Newtonian mechanics is named after a guy named Isaac Newton. He was a really smart man who lived a long time ago. He studied how objects move and wrote lots of important books about it. One of his most famous books is called the "Principia Mathematica."

In his book, Newton explained something really important called the laws of motion. The first law of motion says that objects will stay still or keep moving in a straight line unless a force pushes or pulls on them. The second law says that the harder you push on an object, the faster it will go. And the third law says that for every action, there is an equal and opposite reaction.

These laws help us understand how things move and why they move the way they do. Scientists and engineers use Newtonian mechanics to design new machines, improve technology, and even explore space. So, even though it might seem like just playing with toys, Newtonian mechanics is really important for understanding how the world works.
