Study Notes

Vehicle Dynamics and Safety Concepts

Gravity: A fundamental force that pulls vehicles toward the Earth, influencing their stability and handling.
Friction: The critical gripping action necessary for tires to maintain contact with the road, preventing slippage during driving.
Passive Restraint Device: A safety feature like an airbag that activates automatically in a crash, requiring no manual action from the occupant.
Traction: The essential friction between tires and the roadway that enables vehicles to accelerate, brake, and maneuver effectively.
Tread: The textured surface of tires designed to provide grip on the road, affecting both traction and overall vehicle safety.
Active Restraint Device: A manually adjustable safety belt that the occupant must fasten for protection during a collision.
Banked Curve: A type of roadway curve that rises higher on the outside, helping vehicles maintain speed and stability through turns.
Force of Impact: The amount of force generated when one moving object collides with another, crucial in understanding crash dynamics.
Blowout: A dangerous situation caused by tire wear, leading to a sudden loss of air pressure, which can result in loss of control.
Energy of Motion: Refers to kinetic energy, the energy an object possesses due to its movement, essential in understanding vehicle dynamics.
Center of Gravity: The point within a vehicle where its weight is evenly distributed, influencing handling and rollover risk.
Restraint Device: Any system designed to keep occupants secured in their seats during a collision, enhancing safety.
Total Stopping Distance: The comprehensive distance a vehicle travels from the moment the brakes are applied until it comes to a complete stop.
Perception Time: The initial phase of driver response, where time is taken to identify and assess a hazard before reacting.
Perception Distance: The physical distance covered while a driver is processing and identifying a potential driving hazard.
Reaction Time: The duration it takes a driver to execute the braking or maneuvering action after identifying a hazard.
Braking Distance: The distance traveled from the moment brakes are applied until the vehicle achieves a complete stop, impacted by speed and road conditions.
Reaction Distance: The distance a vehicle travels while a driver identifies a hazard and begins to react, a critical factor in overall stopping distance.
