WebThe explicit inclusion of the motor variable, u, in the R-density and G-density is a key advancement over the standard definition of IFE . Now, using the product rule, p ( ϑ , u ; φ ) = p ( ϑ , u φ ) p ( φ ) for the G -density in equation ( 4.1 ), we decompose the IFE to a form applicable in the biological context: WebScalar Quantities: The physical quantities which are specified with the magnitude or size alone are scalar quantities. For example, length, speed, work, mass, density, etc. Vector Quantities: Vector quantities refer to the physical quantities characterized by the presence of both magnitude as well as direction.
