3.4.9 Equations for a particle in equilibrium (A-level only)

What condition must the forces satisfy for a particle to be in equilibrium?

A

Perpendicular to the surface.

B

Two-dimensional equilibrium gives ∑Fx=0\sum F_x=0∑Fx​=0 and ∑Fy=0\boxed{\sum F_y=0}∑Fy​=0​.

C

Zero acceleration.

D

Their vector sum is zero: ∑F=0\sum \boldsymbol{F}=\boldsymbol{0}∑F=0.
