Resultant Forces (OCR GCSE Physics A, Combined (Gateway Science Suite)): Flashcards

Single force with same effect as all original forces together

Larger force - smaller force

Air resistance and weight

833N down (weight only)

483N down (833 - 350)

Forces equal and balanced, resultant = 0

No acceleration

Forces and their directions acting on an object

Total force acting in that direction

Into parallel and perpendicular components to ground

$F \cos \theta$

$F \sin \theta$

$F^2 = (F \cos \theta)^2 + (F \sin \theta)^2$
