First law of motion:
every object in a state of uniform motion tends to remain in that state of motion unless an external force force is applied to it.
second law of motion:
the relationship between an object's mass m,its accelaration a,and the applied force F is F=ma.accelaration and force are vectors (as indicated by their symbols being displayed in slant bolt font)in this law the direction of the force vector is the same as the direction of the acceleration rector.
third law of motion:
for every action there is an equal and opposite reaction.
