10 cards from this deck
Sum of all translational and rotational forces equals zero
τ=r⊥F\tau = r_{\perp}Fτ=r⊥F
Sum of all torques equals zero: ∑τ=0\sum \tau = 0∑τ=0
Net force equals zero: ∑F=0\sum F = 0∑F=0
Perpendicular distance from pivot to line of action of force
Creates no torque
Centre of mass
Vector (has magnitude and direction: clockwise/anticlockwise)
Force far from pivot creates large torque with small force
Select point where unknown force acts to eliminate it
