Equilibrium of a Body

⚡ Quick Summary
For a body to be in equilibrium, the net force acting on it must be zero.
ΣF = 0
A body is in equilibrium when the net force acting on it is zero. This means that the vector sum of all forces acting on the body must be zero. This principle is often applied when solving problems involving forces, such as those involving springs or buoyant forces.
