Types of equilibrium
If the net force acting on a particle is zero, it is said to be in equilibrium.
Means For equilibrium
Equilibrium of particle can be of three types-
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 the stable equilibrium position.
i.e; rate of change of
is positive
Potential energy is minimum.
For example-A marble placed at the bottom of a hemispherical bowl.
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.
i.e; rate of change of
is negative
Potential energy is maximum.
For 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 neutral equilibrium.
i.e; the rate of change of
is zero.
Potential energy is constant.
For example- A marble placed on a horizontal table.
