... where d2U/dx2>0. For example, for the spring-block, U(x)=1/2kx2 (the solid curve in figure below), x=0 is an equilibrium position because dU/dx=kx=0. And d2U/dx2=k>0, and hence x=0 is an stable equilibrium position. On the other hand, for a system with potential energy, U(x)=-1/2kx2, x=0 is still an ...

... • Find the resultant external force acting on the body causing its motion. It may be necessary to draw a free-body diagram. • Determine the velocity of the point on the body at which the force is applied. Energy methods or the equation of motion and appropriate kinematic relations, may be necessary. ...

Hunting oscillation

Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system ""hunts"" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering.
