Why Inertia?

Aristotle postulated the connection between force and motion in 350 B.C. Galileo furthered these views some 2000 years later. Sir Isaac Newton formalized the concept in 1687. The first of the three laws of motion is the Law of Inertia. The law of inertia states that a body, or mass in motion will continue in that motion until an outside force acts upon it to cause a reaction. Likewise, an object at rest will remain at rest without an external influential force.

Perspective is the key to inertia. Which force is being acted upon, and which is causing the reaction, the inertia of both bodies is changed by their contact with one another. Inertia Engineering and Machine Works strives to be the force of change while reacting to industry needs. We trust that our products will change and improve technology that will make positive impacts on the electrical power distribution industry.
