... Technically, the crane didn’t do any work on the shipping container, but rather the shipping container did work on the crane! Note how we are completely ignoring the crane’s horizontal motion, because this displacement vector is at right angles (90o ) to the container’s weight vector as well as the ...

... Forces acting perpendicular to motion have no affect in the direction of the original motion. They do not speed up or slow the object in the direction being investigated. The object experiences inertia (stays at rest or continues at constant velocity) in the direction it was originally moving. No wo ...

Lesson 3 - Understanding Energy (with a Pendulum)
... Kinetic energy (KE) - due to an object’s velocity Potential energy can be converted to kinetic energy by allowing the object to fall (for example, a roller coaster going down a hill or a book falling off a table). This energy transformation also holds true for a pendulum. As a pendulum swings, its p ...

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.
