What does body force mean? - Definitions.net

WebThe generic body force seen previously is made specific first by breaking it up into two new terms, one to describe forces resulting from stresses and one for "other" forces such as gravity. By examining the forces acting on a small cube in a fluid, it may be shown that where is the stress tensor, and accounts for other body forces present. WebDrag force FD is proportional to the square of the speed of the object. Mathematically, FD = 1 2CρAv2, where C is the drag coefficient, A is the area of the object facing the fluid, and ρ is the density of the fluid. Athletes as well as car designers seek to reduce the drag force to lower their race times ( Figure 6.29 ).
