West Coast EMT Block 4 Study Guide With Complete Correct Answers!

Know Newton's First Law of Motion - ANSWER-The first law states that objects at rest tend to stay at rest and objects in motion tend to stay in motion unless acted upon by an outside force. Kinetic Energy - ANSWER-The energy of a moving object. Reflects the relationship between the mass (weight) of the object and the velocity (speed) at which it is traveling. Potential Energy - ANSWER-The product of mass (weight), force of gravity, and height and is mostly associated with the energy of falling objects. The energy stored within an object. Know the 3 collisions that occur in a car accident. First Collision: - ANSWER-The collision of the car against another car, a tree, or other objects. Does not directly affect patient care except making extrication difficult The damage to the car can indicate how severe the patient's injury is and help determine the mechanism of injury. Know the 3 collisions that occur in a car accident. Second Collision: - ANSWER-The collision of the passenger against the interior of the car. This damage is caused by the kinetic energy produced by the passenger's mass and velocity is converted into the work of stopping the passenger's body.
