Chapter Summary
... The standard method of solving force problems involves splitting the forces into components, applying Newton’s second law once for each direction, and combining the results. However, it should be kept in mind that some problems lend themselves to being solved with whole vectors. The steps in the sta ...

Chapter 6 Work, Kinetic Energy and Potential Energy
... The potential energy U(r) also has units of joules in the SI system. When our physics problems involve forces for which we can have a potential energy function, we usually think about the change in potential energy of the objects rather than the work done by these forces. However for non–conservativ ...

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.
