Paramedic Trauma Latest 2023 Graded A mechanical energy Kinetic or potential energy associated with the motion or position of an object-MVA chemical energy potential energy stored in chemical bonds- battery acid thermal energy Heat energy- burns electrical energy high voltage-lightning strike barometric energy The energy that results from sudden changes in pressure as may occur in a diving accident or sudden decompression in an airplane- explosions kinetics study of speed, mass, direction of force, and physical injury dissipation the larger the area of force _____, the more pressure is reduced to a specific spot velocity distance per unit of time acceleration The rate at which velocity changes-speeding up or slowing down gravity downward acceleration of imparted to any object moving toward earth kinetic energy mass∧2×velocity∧2 energy dissipation Process by which KE is transformed into mechanical energy slowly if a car stops _________, kinetic energy is converted to thermal energy crashes if a car __________, kinetic energy is also converted to mechanical energy phase 1 deceleration of vehicle phase 2 deceleration of occupant deceleration, compression, sheer phase 3 deceleration of internal organs phase 4 secondary collisions objects moving in vehicle phase 5 additional impacts received by the vehicle head-on impacts Passengers decelerate at the same rate as the vehicle Down and Under Pathway Occupant slides under the steering wheel or the dash. The knees hit the dashboard, and transmit energy up the leg, to the femur/pelvis. If the feet are locked in place, it can cause femur fractures Up and Over Pathway Chest hits the steering wheel, head hits the windshield and anterior portion of the throat hits the top of the steering wheel. Can cause significant head and neck injuries. Lateral impact injuries the body is pushed in one direction, while the head moves toward the impacting object rear impact injuries sudden forward accelerating force causes the body to move forward but not the head-whiplash energy is imparted to the front vehicle rotational impact lateral crash is off center vehicles forward motion stops, but the side conti
