I'm sure you've heard of Isaac Newton and maybe of some of his laws. Like, that thing about "equal and opposite reactions" and such. But what do his laws mean? And how do they help us understand the world around us? In this episode of Crash Course Physics, Shini talks to us about just that.

I think most of Newton’s laws kinda disappear once you leave a gravitational orbit. Meaning Newtons law is a SCAM

EINSTEIN HAD STOLEN THE PHYSICS INHERITANCE WILL FROM A FAMILY GAS BOTTLING CO. NAMED E=MC2 ORIGINATED IN THE UK MOVED TO THE US IN 1778 THE PERSON NAME & PRECISE BIRTH DATE TO RECIEVE THE MONEY IS IN THE EQUATION E=MC2 DONE IN SIMPLE ARITHMETIC AND ALPHABETS THE PERSON IS STILL ALIVE BUT HOMELESS CAN YOU CRACK IT?

So what happened on 9/11? How did 20 floors of a building destroy 90 floors below them? I think Newton was a coke chef spinning drivel. Once any mass begins moving as proved by 9/11 all Laws are out of the window.

so why doesn't the earth push me away? my mass is pushing less on the earth than its pushing back on me right?

Newton’s 3rd law contradicts his 1st law: if there is an equal but opposite force to every action (3rd law), then an object remains still *even though* another force acts upon it (contradiction of 1st law, or more accurate description of 1st law). Inertia: An object will remain in motion or remain still, even as force is constantly exerted upon it. Ie: a book remains at rest on the table *because* the force of the table pushes against it (both 3rd law and contradiction of 1st law)

The Game Rules of our Universe
I just started out making videos on physics too, intuitively explaining it's most interesting and essential ideas in a series called "The Game Rules of our Universe". In case you are interested, I would really appreciate you checking out my channel.
