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
