... THEOREM. It basically means that if we impart work to an object it will undergo a CHANGE in speed and thus a change in KINETIC ENERGY. Since both WORK and KINETIC ENERGY are expressed in JOULES, they are EQUIVALENT TERMS! " The net WORK done on an object is equal to the change in kinetic energy of t ...

... For a closed path, the total work done by a non-conservative force is NOT ZERO - as it is for a conservative force. For instance, a frictional force would oppose the motion and “slow” the car down. Unlike gravity, friction would do negative work on the car through out the entire trip, on both the up ...

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.
