TNCC Questions And Answers

Biomechanics - Is the general study of forces & their effects Kinematics - Is the study of energy transfer as it applies to ID'ing actual or potential injuries Mechanism of Injury (MOI) - Is how external forces are transferred to the body, resulting in injury Newton's 1st Law of Motion - A body @ rest, stays @ rest unless acted on by an outside force Newton's Second Law - The acceleration of a body is parallel & directly proportional to the net force acting on the body, is in the direction of the net force, & is inversely proportional to the body's mass Force equals mass times acceleration (It takes more force to move a heavy object vs a light object) Newton's Third Law - For every action there is an equal and opposite reaction Law of conservation of energy - Energy cannot be created or destroyed When mass is doubled - Energy is doubled as well When velocity is doubled - Energy is quadrupled Mechanical energy - The direct impact of an object, such as in a car collision or a pot to the head Thermal energy - The transfer of heat energy, such as a burn from a liquid or hot object like a pot Chemical energy - Heat energy from active chemical substances, such as household cleaners or acids
