Emergency Vehicle Operations (EVOC)
Three (3) main factors that directly impact basic motor vehicle operations are: - Answer--Vehicle
-Driver
-Roadway
Laws of Physics: - Answer-1) Kinetic energy
Energy an object possesses by being in motion.
2) Momentum
Is the combined mass and velocity of an object. An object in motion tends to remain in motion until
acted upon by an outside force.
3) Friction
Is resistance between two objects rubbing against each other.
* Rolling Friction
* Sliding Friction
4) Weight Shift (or Transfer)
Is a change in load placed on vehicle wheels/tires while in motion. More weight over the tire means
more tread is on the road surface. Less weight over the tire is more likely to cause a slide or skid.
* Longitudinal
, Occurs when vehicles are accelerating or braking.
* Lateral
Is side-to-side and occurs when vehicles turn.
5) Centrifugal Force
Centrifugal force pulls a moving object outward from the center of rotation.
6) Centripetal Force
Pulls a moving object inward toward the center of rotation.
Inspections conducted by officers are made when the patrol car is stationary and in motion. - Answer-
True
Vehicle Inspection Process - Answer-1) Maintenance
2) Exterior
3) Engine Compartment
4) Tires
5) Breaks
6) Interior
7) Trunk
8) Performance and Response (In Motion)
Human error is responsible for 90% of all vehicle crashes, which makes drivers the most critical factor in
motor vehicle operations. - Answer-True
