What is difference between stable unstable and neutral equilibrium?
Differentiate between Stable, Unstable and Neutral equilibrium….1 Answer.
| Stable | Unstable | Neutral |
|---|---|---|
| Potential energy is minimum. | Potential energy is maximum. | Potential energy is constant. |
| F = – dU/dx = 0 | F = – dU/dx = 0 | F = – dU/dx = 0 |
What is the difference between equilibrium and stable equilibrium?
Stability and equilibrium Stability refers to the state of rest of a body while equilibrium is the state of balance of a body. When a body is in equilibrium, it stays in that position as long as there is no external influence on it.
What is a stable or unstable equilibrium?
The difference between stable and unstable equilibria is in the slope of the line on the phase plot near the equilibrium point. Stable equilibria are characterized by a negative slope (negative feedback) whereas unstable equilibria are characterized by a positive slope (positive feedback).
What is stable unstable and neutral equilibrium Class 11?
If the force is restoring i,e direction is towards the equilibrium position then it is a stable equilibrium. if the force is away i,e direction is away from the equilibrium position then it is an unstable equilibrium. If no force acting then neutral equilibrium. Equilibrium And Potential energy.
What is a neutral equilibrium?
When the center of gravity of a body lies at the point of suspension or support, the body is said to be in neutral equilibrium. Example: rolling ball. Explanation. If a ball is pushed slightly to roll, it will neither come back to its original nor it will roll forward rather it will remain at rest.
What is an example of unstable equilibrium?
When the ice cream cone is made to rest on its apex on a book, the movement of the book will disturb the position of the ice cream cone. This is an example of unstable equilibrium.
What are the examples of neutral equilibrium?
5 examples of neutral equilibrium
- Ball moving on the ground.
- Motion of sphere.
- A roller.
- A pencil lying horizontally.
- An egg lying horizontally on a flat surface.
What is stable equilibrium example?
5 examples of stable equilibrium chair lying on the floor. the heavy base of the vehicle. table lying on the ground. Cone lying on its base by lowering its center of gravity. Bottle lying on its base.
What is the condition of stable equilibrium?
equilibrium is said to be stable if small, externally induced displacements from that state produce forces that tend to oppose the displacement and return the body or particle to the equilibrium state. Examples include a weight suspended by a spring or a brick lying on a level surface.
What is neutral equilibrium?
A condition of a system for which a small perturbation of a parcel of the system causes it to neither depart from its new position nor return to its previous one.
What is neutral stability?
A stable atmospheric condition that exists in dry air when the environmental lapse rate equals the dry adiabatic rate, and in moist air when the environmental lapse rate equals the saturated adiabatic rate. From: neutral stability in A Dictionary of Environment and Conservation ยป
What is unstable equilibrium with example?
A system is in unstable equilibrium if, when displaced, it experiences a net force or torque in the same direction as the displacement from equilibrium. A system in unstable equilibrium accelerates away from its equilibrium position if displaced even slightly. An obvious example is a ball resting on top of a hill.
