Resultant Forces (AQA GCSE Physics Combined Science): Flashcards

Single force with same effect as all original forces together

Larger force - smaller force

Add the forces together

Subtract the forces

Air resistance and weight

833N down (only weight acting)

Air resistance increases

0 (zero)

When resultant force is 0 (no acceleration)

Forces and their directions acting on an object

Parallel and perpendicular to the ground

$a^2 + b^2 = c^2$

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