... In physics we use different quantities to describe the observed phenomena. Among them the most important are scalars and vectors. Scalars are simply the numbers, which describe for example the temperature, mass, density, energy. Other physical phenomena cannot be described in terms of simple numbers ...

... In general, the work done by the force depends on the path between r0 to r1 . For some special forces, however, the work done is independent of the path. Such forces are said to be conservative. For a force to be conservative: The force must be a function only of its position – i.e. it can’t depend ...
