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

Net force equals zero, $\vec{F}_{\text{net}} = 0$

At rest (stationary) or moving at constant velocity

Zero acceleration

Normal force upward = Gravitational force downward

Different objects, not the same object

$F_{\text{net},x} = 0$ and $F_{\text{net},y} = 0$

$F \cos\theta$

$F \sin\theta$

Net force is zero AND object is at rest

Friction force = Air resistance
