Resolving Forces & Inclined Planes (Edexcel A-Level Mathematics): Flashcards

Smooth

$mg \sin \theta$

$mg \cos \theta$

Parallel and perpendicular to slope

Equilibrium

Normal reaction force perpendicular to slope

$F = ma$ or $\sum F = ma$

Tension same on both sides of pulley

Parallel to plane, opposes motion

$F_{\text{friction}} = \mu F_{\text{normal}}$

Force due to gravity (weight)

Parallel and perpendicular to the plane
