Concept of stable, unstable, static and dynamic, Partial and General equilibrium Equilibrium: If an object is said to be in a state of equilibrium, then all the forces which act upon the object are balanced. It is defined as the state of rest due to the equal action of the opposing forces. Stable equilibrium: When a particle is displaced slightly from a position, then a force acting on it brings it back to the initial position, it is said to be in stable equilibrium position. Example: A marble placed at the bottom of a Unstable equilibrium: When a particle is displaced slightly from a position, then a force acting on it tries to displace the particle further away from the equilibrium position, it is said to be in unstable equilibrium. Example: A marble balanced on top of a hemispherical bowl. Neutral equilibrium: When a particle is slightly displaced from a position then it does not experience any force acting on it and continues to be in equilibrium in the displaced position, it is said to be in Dynamic equilibrium This is the type of equilibrium in which the resultant of all the forces acting on the body is zero, i.e. the net acceleration of the body is zero, but the velocity of the body is not zero. It means that the body is moving with a constant velocity. So if the net Static equilibrium This is the type of equilibrium in which the resultant of all the forces acting on the body is zero, i.e. the net acceleration of the body is zero, and the velocity of the body is also zero. It means that the body is at rest. So if a body is at rest and the net acceleration of it is zero, it means the
