Newton’s Laws of Motion

I am going to explain to Newtow’s Laws of motion how it works examples and more. So lets start with how it works everywhere we go the is Newton’s Law if you run, sleep, drink water, and even playing sport.

Well Newton’s first law or law of inertia as to do with any object that is not moving will not move until a force acts upon it and also if you put applied force on an object it will go in the direction it was hit until stopped by an opposing force. Just like when was sitting under that tree the apple fell from the tree and it kept going until it hit his head that was the opposing force. Too bad for Newton’s head it sucks for him because there was no advil back then.

Newton’s second law of motion is all about the relationship between an object’s mass m, it’s acceleration a, and the applied force f is f=ma. Acceleration and force are vectors in this law the direction of the acceleration vector. This law has to do more with formulas and solving for the acceleration, mass, and force. This law is not as similar as the rest of them law number one and two.

For action there is an equal and opposite reaction this is a perfect example if you a touch someone there are touching you too that’s the reaction force. This law has to do with more of friction, kinetic friction, and static friction. Friction is the force that slows down an object while it is moving. Kinetic friction is friction applied to a moving object. Static friction is a the force that bonds objects together like when you hug someone you in static friction.

If it was not for Newton’s force we would not understand how to things move why they do not move and how to find the mass, acceleration, and force of an object. With this we have improved the way we think about science so thank you Newton for your positive thinking on force, friction, and gravity. Science would not be great without great scientists like you.
