Chapter 12 drivers Ed

Inertia

1. Moving objects continue to move in a straight line unless some force acts on them. 2.Objects at rest do not move unless some force acts on them

Using Appropriate Speed

In order to use appropriate speed you need to constantly be aware of your visibility, traction, and pace

Visibility

To manage visibility make sure large objects aren't in the way of your view/ keep sunglasses in case of glare

Steering and Braking

Your ability to steer a vehicle depends partly upon the condition of the vehicles suspension/ braking is a result of friction between the brake linings and wheel drums or discs

Gravity

a force that pulls all objects toward the center of the Earth

Directional control

a vehicle's ability to hold a straight line or to continue in a particular direction

Natural laws/ Movement of your vehicle

forces in nature that are always at work; Natural laws that affect you as a driver include inertia, friction, momentum, kinetic energy, and gravity

Total Stopping Distance

made up of three components: Human-perception distance, Human-reaction distance, Vehicle-Braking distance. All three components factor in how long it takes to come to a complete stop.

Centrifugal force

pushes you in the direction opposite to the way you are turning

Friction

the force between two surfaces that resists the movement of one across the other/the force that seems to hold the two surfaces together

Momentum

the quality of motion in a moving object, a combination of its and its speed
