... A conservative force is a force with the property that the work done in moving a particle between two points is independent of the path taken…only matters on initial and final positions. ie; Gravity & spring force. A non-conservative force is a force with the property that the work done in moving a ...

... The total work is zero, since the forces cancel out in the direction of motion. Similarly, ΔK = 0 since the object is at rest at the top and bottom. The work we have done on the block has not resulted in a change in kinetic energy! Even though this is a nice consistent picture, we find it unsatisfac ...

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.
