**Defined in theory: Standard-dimensions****Source code: standard-dimensions.lisp**

**Documentation:**The physical dimension of force is defined as mass times length over time squared. In some systems FORCE-DIMENSION is fundamental and MASS-DIMENSION is a derived dimension. This theory goes with the SI standard, but we include the definition of force as a non-fundamental built-in dimension.

**Instance-Of:**Physical-dimension

(= Force-Dimension (* Mass-Dimension (* Length-Dimension (Expt Time-Dimension -2))))
