👉 Shiftage is a concept in physics and engineering that refers to the movement of matter (such as a material or an object) due to a change in its position relative to another object. This can be thought of as the displacement of a point from its original location, which is called the reference point. In physics, shiftage can be seen as a fundamental property of objects and materials that allows them to undergo significant changes in their properties (such as density or volume) without altering their initial position.
