In algebraic geometry, a relative cycle is a type of algebraic cycle on a scheme. In particular, let be a scheme of finite type over a Noetherian scheme , so that . Then a relative cycle is a cycle on which lies over the generic points of , such that the cycle has a well-defined specialization to any fiber of the projection . The notion was introduced by Andrei Suslin and Vladimir Voevodsky in 2000; the authors were motivated to overcome some of the deficiencies of sheaves with transfers. (Wikipedia).

Simple Harmonic Motion (1 of 16): Period of a Pendulum
This video uses one of the simulations from PhET Interactive Simulation to investigate how changing the mass, length, displacement and gravity of the pendulum affects its period. A pendulum is a mass suspended from a string that is attached to pivot point. There is no friction so that the
