Each of these systems has an equilibrium or rest position. Now assume that the mass in either figure is given an initial displacement and then released so that it may vibrate freely. The massm = massL = lengthg = gravityθ = angular displacement...
Static Equilibrium If an object at rest is acted upon by opposing influences that are internal, external, or both in such a way that the object remains in that position only, then the object is said to be in static equilibrium. A few examples of static equilibrium are: An apple hanging ...

Reflective equilibrium (“RE” for short) is by now well-known in philosophy. It was first proposed by Goodman (1983) as an answer to the question of how to justify (deductive and inductive) inferences and principles of inference. Later, Rawls (1999), to whom we owe the term “reflective...
Is a force always necessary to make an object initially at rest start moving? (a) Yes (b) No (c) It depends on the mass of the object. When an object is at rest, does any frictional force act on it? An object is not considered to be in a state if equilibri...
