Newton’s Laws of Motion, as written in his book his book the Principia.On July 5, 1687
The First Law (The Law of Inertia) :
“Every body continues in a state of rest or uniform velocity in a straight line, unless an external force acts on it.”
An object resisting a change in its “state of motion” (stopped or moving in a straight line) is something that Newton called inertia. That’s why this law is sometimes called the Law of Inertia.
The idea of inertia is confirm us if an object is moving right now, it will keep on moving in the direction of force.
It is not necessarily you see this because of the effects of friction.
If you roll a ball across the floor it will slow down and eventually stop.
This is not because it is violating inertia, but because there is an external force acting on it--- friction.
Why people are injured in car accidents when they do not wear seat belts?
In the car the person try to be in inertia of motion, so the person will continue to move forward at the same speed as the car was originally traveling and hit car .
Newton’s First Law goes against what Aristotle said, but is basically what Galileo had said a few years earlier.

Aristotle had said that if you stop pushing an object, it will come to rest. He believed that “at rest” was the natural state for any object.
Galileo told us to ignore friction and basically came up with Newton’s First Law. It is called Newton’s First Law because he was the one that formally published it and had the mathematical proofs to back it up.
