- 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.

A rigid body is supposed to be in equilibrium if there is no change in translational motion and no change in rotational motion General conditions for equilibrium are as follows (i) The total force must be zero (ii) The total torque about any axis must be zero. Sometimes it is convenient to consider torques about axes through the center of gravity.
We can divide the equilibrium into two categories with respect to the state of a body 1. Static equilibrium. 2. Dynamic equilibrium. Static equilibrium If the total force and total torque on the body are zero and the body is in the state of rest then its equilibrium is termed as static equilibrium. For example All stationary bodies Dynamic equilibr...
If only conservative forces are acting on the system, then we can define equilibrium in terms of Potential energyalso For 1D motion, we can write it like dU=−FxdxdU=−Fxdx Now For equilibrium, Force should be zero Then Fx=−dUdx=0Fx=−dUdx=0 For stable equilibrium, the second derivative should be positive. So for slight displacement, the restoring for...

(1) The potential energy function of the object confined to move along x-axis x> 0 is given below U(x)=U0[(kx)12−2(kx)6]U(x)=U0[(kx)12−2(kx)6] Here k > 0 and U0U0> 0 Find the equilibrium position and find out if it is stable,neutral and unstable equilibrium? Solution Now U(x)=U0[(kx)12−2(kx)6]U(x)=U0[(kx)12−2(kx)6] Differentiating with respect to x...
The stable equilibrium should be at lower potential then any nearby point. The unstable equilibrium should be at higher potential energy than any nearby point. The neutral equilibrium should have the same potential energy as nearby points.
Oct 31, 2023 · So I have read that a particle is in Stable Equilibrium when the potential energy is minimum, Unstable Equilibrium when the potential energy is maximum and Neutral Equilibrium when the potential energy is neither maximum or minimum. All of these definitions have the condition that net force on the particle = 0 0 (or the particle is at ...
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.
Equilibrium is defined by no net forces or torques. Stability of an equilibrium can be determined by the second derivative of the potential. Defining a center of mass allows a simple way to study the behavior of a system or object as a whole. Stable equilibrium requires a restoring force.
Stable objects are very difficult to topple over, while unstable objects topple over very easily. Key fact An object will topple over if its centre of gravity is ‘outside’ the base, or edge ...
