The coefficient of restitution (COR) of two colliding objects is typically a positive real number between 0.0 and 1.0 ... more

The terms “relative change” and “relative difference” are used to compare two quantities while taking into account the ... more

Optical magnification is the ratio between the apparent size of an object (or its size in an image) and its true size, and thus it is a dimensionless ... more

A triangle wave is a non-sinusoidal waveform named for its triangular shape. It is a periodic, piecewise linear, continuous real function. Like a square ... more

Electric flux is the rate of flow of the electric field through a given area. Electric flux is proportional to the number of electric field lines going ... more
