Force Diagrams (Grade 11 NSC Matric Physical Sciences): Flashcards

Visual representations showing forces on objects using arrows

Strength (magnitude) of the force

Object as dot with forces as arrows pointing away from it

$F_{gx} = F_g \sin(\theta)$

$F_{gy} = F_g \cos(\theta)$

Angle of inclination from the horizontal

Tries to slide the object down the plane

Presses the object into the surface

Arrows must touch the system or object

Parallel component
