2026 COMPLETE QUESTIONS AND CORRECT
ANSWERS
◉ chemical energy. Answer: potential energy stored in chemical bonds-
battery acid
◉ thermal energy. Answer: Heat energy- burns
◉ electrical energy. Answer: high voltage-lightning strike
◉ barometric energy. Answer: The energy that results from sudden
changes in pressure as may occur in a diving accident or sudden
decompression in an airplane- explosions
◉ kinetics. Answer: study of speed, mass, direction of force, and
physical injury
◉ dissipation. Answer: the larger the area of force _____, the more
pressure is reduced to a specific spot
,◉ velocity. Answer: distance per unit of time
◉ acceleration. Answer: The rate at which velocity changes-speeding up
or slowing down
◉ gravity. Answer: downward acceleration of imparted to any object
moving toward earth
◉ kinetic energy. Answer: mass∧2×velocity∧2
◉ energy dissipation. Answer: Process by which KE is transformed into
mechanical energy
◉ slowly. Answer: if a car stops _________, kinetic energy is converted
to thermal energy
◉ crashes. Answer: if a car __________, kinetic energy is also
converted to mechanical energy
◉ phase 1. Answer: deceleration of vehicle
◉ phase 2. Answer: deceleration of occupant
deceleration, compression, sheer
, ◉ phase 3. Answer: deceleration of internal organs
◉ phase 4. Answer: secondary collisions
objects moving in vehicle
◉ phase 5. Answer: additional impacts received by the vehicle
◉ head-on impacts. Answer: Passengers decelerate at the same rate as
the vehicle
◉ Down and Under Pathway. Answer: 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. Answer: 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. Answer: the body is pushed in one direction,
while the head moves toward the impacting object
