Circular Motion
... • The centripetal acceleration always points toward the center of the circle. ALWAYS! • Since the acceleration is toward the center on the circle the net force causing the acceleration must also point toward the center of the circle. This net force is called the Centripetal Force because it causes t ...

... should depend on why that position has energy. The water stored behind a dam has energy due to it’s height above the base of the dam. We can use this to run a hydroelectric station. The energy in food is due to the molecular binding of the atoms in the food. The same is true for coal, oil and gas. T ...

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.
