1. Every object in a state of motion tends to remain in that state of motion unless an external force is applied to it.
2. The relationship between an objects mass m, accelaration a, and the applied force f is f=ma. Accelaration and force are vectors (as indicated by thier symbols being displayed in a slant bold font) in this law the direction of the force vector is the same as the direction of the eccelaration vector.
3. For every action there is an equal and oppisite reaction.
