Energy of a Free Rolling Cart on an Inclined Plane
... released it has kinetic energy, KE. As it rises up the incline it slows down, loses kinetic energy, and gains gravitational potential energy, PE. As it starts down, still rolling freely, the stored gravitational potential energy is converted back into kinetic energy as the cart falls. If there is no ...

5/06 Gravitational Energy Conservation Figure 1 A
... Forces acting ON the bob are: gravity (down), and tension (along the string).These both act to produce acceleration. But only gravity does work on the bob, because the tension is always at right angles to the direction of motion (velocity vector), i.e., the cosine factor is always zero. If you pause ...

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.
