Card 1 of 20
What quantity determines whether forces acting on an object are balanced?
A
In two dimensions, equilibrium requires ∑Fx=0\boxed{\sum F_x=0}∑Fx=0 and ∑Fy=0\sum F_y=0∑Fy=0.
B
The resultant force is the vector sum of all forces and has the same overall effect as them.
C
The resultant force.
D
Yes - their vector sum must be zero.
