Emergency Vehicle Operations (EVOC) UPDATED ACTUAL Questions and
CORRECT Answers
-Vehicle
Three (3) main factors that directly impact basic motor
-Driver
vehicle operations are:
-Roadway
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
Laws of Physics:
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
