inertia - (physics) the tendency of a body to maintain its state of rest or uniform motion unless acted upon by an external force. natural philosophy, physics - the science of matter and energy and their interactions; his favorite subject was physics.
Inertia is scientific principle and not a property of matter. It is not quantifiable in the way you are suggesting, and it has no units. Inertia is the principle that a body will continue to move in the same way (that is, at the same velocity) unless acted on by a force.he mass of a body determines the momentum P of the body at given velocity v; it is a proportionality factor in the formula: P = mv The factor m is referred to as inertial mass.
