- A system is said to be in stable equilibrium if, when displaced from equilibrium, it experiences a net force or torque in a direction opposite the direction of the displacement. A system is in unstable equilibrium if, when displaced from equilibrium, it experiences a net force or torque in the same direction as the displacement from equilibrium.

A system is said to be in stable equilibrium if, when displaced from equilibrium, it experiences a net force or torque in a direction opposite to the direction of the displacement. For example, a marble at the bottom of a bowl will experience a restoring force when displaced from its equilibrium position.

4 days ago · Eigenvalues can be used to determine whether a fixed point (also known as an equilibrium point) is stable or unstable. A stable fixed point is such that a system can be initially disturbed around its fixed point yet eventually return to its original location and remain there.
Equilibrium requires that the coefficients of ΔS and ΔV both vanish, that T = (∂E ∂S) ∗ V, N = T ∗ 0 and p = − (∂E ∂V) ∗ S, N = p ∗ 0 . The condition for stability is that ΔG> 0 for all (ΔS, ΔV). Stability therefore requires that the Hessian matrix Q be positive definite, with. Q = (∂2E ∂S2 ∂2E ∂S∂V ∂2E ∂S ...
When the first derivative is zero, we can take the second derivative to find whether the equilibrium is stable or unstable. Explicitly, if the potential is concave-up at x 0, d2U (x) dx2 | x0> 0, then the system is stable; conversely, if the potential is concave-down, then the equilibrium is unstable.
When a system is in stable equilibrium, any small displacement or perturbation results in forces that act to restore the system to its equilibrium state, demonstrating resilience. This concept is closely linked to potential energy, as the potential energy of the system is at a minimum at this point, making it favorable for stability.
