Question

the equation of motion could be written as equilibrium equation simply by introducing inertia force in addition to real force acting on the system the idea is known as​

Answer 1

Explanation:

define net force, external force, and system. ... Before we can write down Newton's second law as a simple equation giving the ... the mass (the inertia), the smaller the acceleration produced by a given force

Answer 2

Answer:

D'Alembert's law

Explanation:

• According to Newton's second law of motion, i.e.

Force (F)= mass (m) × acceleration(a)

i.e. F=ma

• Alternatively, this can be written as F-ma= 0 as per the law proposed by a French mathematician and physicist J.R d'Alembert.

• This Principle is based on the virtual work along with its forces in inertia which states that,

• "For a system of mass of particles, the sum total of the differences between the impressed forces and the real forces on the system and the time derivatives of the momenta vanishes and becomes zero when subjected to any virtual displacement (which is reversible in nature)."

Hence the equation of motion could be written as an equilibrium equation simply by introducing inertia force in addition to the real force acting on the system the idea is known as​ D'Alembert's law.
