Building models doesn't actually help scientists observe phenomena. Scientists build models to describe how nature and systems operate then make observations to see if their models match what they observe. Models which don't match what they observe are either alterated or scrapped. Good models are kept and used by the scientific community.
<span>The point at which the brakes begin to slow the vehicle is called the braking point. Technically speaking the brakes do not actually stop the vehicle, the vehicle is stopped by friction. The brakes stop the wheels and this process begins with the disc brake system. When the brake pad contacts the rotating brake disc it causes the vehicle to slow down due to friction.</span>
