Equilibrium is the condition of a system when neither its state of motion nor its internal energy state tends to change with time. For a single particle, equilibrium arises if the vector sum of all forces acting upon the particle is zero. Elasticity is the ability of a deformed material body to return to its original shape and size when the forces causing the deformation are removed. A body with this ability behaves (or responds) elastically.
