When an object is at rest, it might have several forces acting on it. However,
A) the forces are all in the same direction.
B) there can only be one force opposite gravity, since weight depends on mass.
C) the forces balance out to net force of zero.
D) dynamic equilibrium can never be achieved except in the total absence of all forces.

According to Newton's first law of motion, an object at rest will remain at rest unless acted upon by an unbalanced force. Therefore, the forces acting on an object at rest may be in different directions and magnitudes. However, for the object to remain at rest, the forces must balance out to a net force of zero. This is known as static equilibrium.
