Net Force in One and Two Dimensions (HSC SSCE Physics): Flashcards

Vector sum of all individual forces acting on an object

Object's acceleration

$\vec{a} = \frac{\sum \vec{F}}{m}$

Sum of magnitudes

Difference of magnitudes, direction of larger force

$F_{\text{net}} = \sqrt{F_x^2 + F_y^2}$

$\tan \theta = \frac{F_y}{F_x}$

$F_x = F \cos \theta$

$F_y = F \sin \theta$

$\vec{F}_{\text{A on B}} = -\vec{F}_{\text{B on A}}$
