Newtons 3 Laws of Motion
What are the Three Laws?
1st- An object at rest stays at rest until acted upon by another object
2nd- acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object
3rd- Every action has an equal and opposite reaction
See, if I were to describe motion... It would probably take me much longer than 3 sentences. That's how smart he was. :)
