Defining axes
The perpendicular force resulting from the surface on which an object is resting
Normal force
F_N = F_g = mg
Tangent of the angle at which the object begins to slip

First Law
Inertia
Objects will remain in their original state of motion unless acted upon by an unbalanced external force
