Equilibrium in 1D (AQA A-Level Mathematics): Flashcards

$\sum F = 0$ (net/resultant force equals zero)

$\sum F = 0$

$F_{\text{right}} = F_{\text{left}}$

Stationary or constant velocity

$W = N$ (weight equals normal force)

Object accelerates

$20$ N to the right (not in equilibrium)

Whether object is stationary, constant velocity, or accelerates

Cancel each other out (no net force)
