what is inertia?
Asked by Maria | 22 Sep, 2012, 09:28: PM
answered-by-expert Expert Answer
An object cannot change its state of rest or state of uniform motion in a straight line by itself. In other words, all objects resist a change in their state of rest or motion.
This tendency of objects to resist or oppose change in their state of rest or motion is called inertia.
Mass of an object is the measure of its inertia.
