How does inertia affect an objects motion?
Inertia is the resistance an object has to a change in its state of motion. In common usage, however, people may also use the term “inertia” to refer to an object’s “amount of resistance to change in velocity” (which is quantified by its mass), and sometimes its momentum, depending on context (e.g. “this object has a lot of inertia”). The term “inertia” is more properly understood as a shorthand for “the principle of inertia” as described by Newton in Newton’s First Law of Motion which, expressed simply, says: “An object that is not subject to any outside forces moves at a constant velocity, covering equal distances in equal times along a straight-line path.” In even simpler terms, inertia means “A body in motion tends to remain in motion, a body at rest tends to remain at rest.” On the surface of the Earth the nature of inertia is often masked by the effects of friction which brings moving objects to rest relatively quickly unless they are coasting on wheels, well lubricated or perhap
