Newton's Laws of Motion
1st Law
An object at rest tends to stay at rest.
In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force. Mathmatically defined as $F_{net} = ma$ where $F_{net} = 0$.
2nd Law
An object in motion tends to stay in motion.
In an inertial frame of reference, the vector sum of the forces $F_{net}$ on an object is equal to the mass $m$ of that object multiplied by the acceleration a of the object. Mathmatically the same as the first law: $F_{net} = ma$1), but where $F_{net} \ne 0$.
3rd Law
Every action has an equal and opposite reaction.
Rest of definition please
1)
It is assumed here that the mass $m$ is constant
