A stable equilibrium state is a state in which a system is at rest or in motion with a constant velocity, and any disturbances or external forces acting on the system will not cause it to deviate from its current state.
The factors that determine if a system is in a stable equilibrium state include the system's mass, shape, and the forces acting on it. A system will be in a stable equilibrium state if the forces acting on it are balanced and there is no net torque or change in energy.
In theory, a system can remain in a stable equilibrium state forever if there are no external forces or disturbances acting on it. However, in the real world, there is always some degree of friction or external forces that can cause the system to eventually lose its stable equilibrium state.
Some examples of systems in a stable equilibrium state include a pendulum at rest, a book sitting on a table, and a ball rolling at a constant speed on a flat surface. In each of these examples, the forces acting on the system are balanced, and there is no net torque or change in energy.
A stable equilibrium state is a state in which a system is at rest or in motion with a constant velocity and will return to its original state if disturbed. In contrast, an unstable equilibrium state is a state in which a small disturbance can cause the system to move away from its original state and not return to it. An example of an unstable equilibrium state is a pencil standing on its tip.
