Physics

________- Originally, natural sciences or natural philosophy, The science of dealing with properties, changes, interaction, etc., of matter and energy.

Rectangular Resolution

________- This is done by resolving all vectors into rectangular components along any convenient pair of axes and then combine these into a single resultant.

Equilibrium
