Chapter 6 Energy
... Work is a measure of energy transfer. In the absence of friction, when positive work is done on an object, there will be an increase in its kinetic or potential energy. In order to do work on an object, it is necessary to apply a force along or against the direction of the object’s motion. If the fo ...

... Part 2: Energy Stored in a Spring (Potential Energy) THEORY: In this part of the experiment we will test the equation for the energy stored in a spring. Let's take down to be the positive direction so that the force exerted on the hanging mass can be written as Fx = -k(x-xo). Note that if the spring ...

2.1 Inertial Frames of Reference
... Definition. A frame of reference is a system of spatial coordinates and possibly a temporal coordinate. A frame of reference in which the Law of Inertia holds is an inertial frame or inertial system. An observer at rest (i.e. with zero velocity) in such a system is an inertial observer. Note. The ma ...

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.
