17.4 Inertia and Newton`s 1st law of motion
... moving, it resists being slowed down, speeded up, or changed in direction. The tendency of mass to keep doing whatever it is – standing still or moving in a straight line – is called inertia. Inertia is almost the same thing as mass – the more the mass the more the inertia. The diagram (right) shows ...
