Newtons law of motion

Answer 1

There are three law's of motion.

1. Every object in a state of uniform motion will remain in that state until an external force is applied to that object. This is commonly referred to as the Law of Inertia.

2. Every object of mass that has an external force applied to it will result in an acceleration along the direction of the applied force on the mass that is inversely proportional to the mass. F/m=a or F=ma. That is the so-called 'weak' definition. A stronger form is; force is equal to the first time derivative of the objects momentum. F=d/dt(mv), where F is force, d/dt is the first time derivative, m is the mass, and v is the relative velocity.

3. For any force applied to an object there exists a reactionary force equal in magnitude but opposite in direction the the applied force. Colloquially known as, for every action there is an equal and opposite reaction. Sometimes referred to as the action-reaction law in introductory physics classes.

Answer 2

Sir Isaac newton had three laws. if you want to know more about the different laws ask a question about Newton's first, second, or third law of motion!!!!!
