Answer 1

Answer:

of which chapter Is this ????

Answer 2

In physics, a moment is an expression involving the product of a distance and another physical quantity, and in this way it accounts for how the physical quantity is located or arranged.

Moments are usually defined with respect to a fixed reference point and deal with physical quantities measured at some distance relative to that reference point. For example, the moment of force acting on an object, often called torque, is the product of the force and the distance to the object from the reference point. In principle, any physical quantity can be multiplied by a distance to produce a moment. Commonly used quantities include forces, masses, areas, and electric charge distributions.
