Definition:Pendulum/Ideals

Definition
The ideals of a pendulum are as follows:


 * The rod is of zero thickness, infinite stiffness and zero mass.


 * The pivot is immovable and has zero friction.


 * The bob is of zero volume.


 * The gravitation field is (usually) taken to be constant and uniform.


 * The medium in which the pendulum moves offers no resistive force, unless otherwise specifically stated.
