Mechanism of injury Flashcards
What is motion injury is caused by?
The body’s absorption of energy
Why do paramedics need to consider the kinetics of trauma?
Helps to predict type of assessments and extent of injuries as well as decisions about priority, treatment, and transport.
What is Newton’s first law of motion?
An object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an outside force.
What is the definition of acceleration?
The rate at which a body in motion increases its speed.
What is the definition of deceleration?
The rate at which a body in motion decreases its speed.
The faster the change of speed, the ____ the force acting on the object.
Greater
