Finding the Resultant Force (Grade 11 NSC Matric Physical Sciences): Flashcards

Single force with same effect as all forces combined

Shows all forces on object using arrows (length = magnitude)

Which way the force acts

$F_R = F_1 + F_2 + F_3 + ...$ (algebraic sum)

Right or up

Force acts opposite to chosen positive direction

Forces are balanced; no net force on object

Algebraic addition with consistent positive direction

Component resolution method

$-2$ N (means 2 N to the left)
