17: Blunt Trauma

Question 1

The branch of physics that deals with motion, taking into consideration mass, velocity, and force.

Answer 1

Kinetics

Question 2

Tendency of an object to remain at rest or remain in motion unless acted on by an external force.

Answer 2

Inertia

Question 3

The process of changing place; movement.

Answer 3

Motion

Question 4

The capacity to do work.

Answer 4

Energy

Question 5

The energy an object has while it is in motion. It is related to the object’s mass and velocity.

Answer 5

Kinetic Energy
NOTE: Increasing mass directly increases kinetic energy, while increasing velocity exponentially increases kinetic energy.

Question 6

A measure of the matter that an object contains; the property of a physical body that gives the body inertia.

Answer 6

Mass

Question 7

The rate of motion in a particular direction in relation to time.

Answer 7

Velocity

Question 8

The rate at which speed or velocity increases.

Answer 8

Acceleration

Question 9

The rate at which speed or velocity decreases.

Answer 9

Deceleration

Question 10

The draining of blood to the point at which life cannot be sustained.

Answer 10

Exsanguination

Question 11

Application of the forces of trauma along the axis of the spine; this often results in compression fractures.

Answer 11

Axial Loading

Question 12

The region of a vehicle designed to absorb the energy of impact.

Answer 12

Crumple Zone
