Inertia

INERTIA (MASS) An object in motions stays in motion, unless no other external force is acting upon it. Newtons first law of motion basically explains inertia. It is an objects resistance to any change in motion. For example, when a car is going 40 mph and then suddenly screeches to a halt, the people in the car may fly forward in their seats, because their bodies are resisting a change in motion (the car slowing down). The mass of an object is a measure of its inertia. The greater the mass, the more inertia (example, trying to bowl a strike, not letting go of the bowling ball, and then flying forward with it, woohoo mass of the bowling ball!)

Inertia and Mass
[|Newton's first law of motion] states that "An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force." Objects tend to "keep on doing what they're doing." In fact, it is the natural tendency of objects to resist changes in their state of motion. This tendency to resist changes in their state of motion is described as **inertia**.

Inertia: the resistance an object has to a change in its state of motion.  [|Bibliography]
