Emergency Vehicle Operations (EVOC) Latest Questions and Answers 2024

Three (3) main factors that directly impact basic motor vehicle operations are: - -Vehicle -Driver -Roadway Laws of Physics: - 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.
