*Fr.: analyse dimensionnelle*
A technique used in physics based on the fact that the various terms in a
physical equation must have identical → *dimensional formula*e
if the equation is to be true for all consistent systems of unit. Its main uses are:
a) To test the probable correctness of an equation between physical quantities.
b) To provide a safe method of changing the units in a physical quantity.
c) To solve partially a physical probable whose direct solution cannot be achieved
by normal methods. → *dimensional*; → *analysis*. |
