D-Alembert's principle, stated by the 18th-century French polymath Jean le Rond D-Alembert. In effect, the principle reduces a problem in dynamics to a problem in statics. The second law states that the force F acting on a body is equal to the product of the mass m and acceleration 'a' of the body, or F = ma; in D-Alembert's form, the force F plus the negative of the mass m times acceleration a of the body is equal to zero: F - ma = 0.
In other words, the body is in equilibrium under the action of the real force F and the fictitious force -ma. The fictitious force is also called an inertial force and a reversed effective force.
