Volume 4 Chapter 2

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

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

Process of changing place, moving

The capacity to do work in the strict physical sense

The energy and object has while it is in motion. Related to mass and velocity

Measure of matter that an object contains.

Rate of motion in a particular direction in relation to time

KE= mass (weight) x velocity (speed)^2/2

Force= mass (weight) x acceleration (or deceleration)

The rate at which speed or velocity increases

The rate at which speed or velocity decerases

• Compression
• Stretch
• Shear

• Vehicle crash
• Body crash
• Organ crash
• Secondary crash
• Additional impacts

• Rotational
• Frontal
• Lateral
• Rear-end
• Rollover

• Up and over pathway
• Down and under pathway
• Ejection

Application of force along the axis of the spine

Region of the vehicle designed to absorb engergy of impact

Having a slanted position or direction

An agent that enhances fuel combustion

• Pressure wave
• Blast wind
• Projectiles
• Personnel displacement
• Confined spaces and structural collapses
• Burns

Area of overpressure that radiates outward from and explosion

Rapid increase then decrease in atmospheric pressure from an explosion

Air movement caused as the heated and pressurized products of an explosion move outward

Military weapons or muitions

Arrow shaped projectiles found in some military ordnance

An agent that combusts easily or creates combustion

• Primary- heat of explosion and overpressure wave
• Secondary- blast projectiles
• Tertiary- personnel displacement and structural collapes

Undissolved solid, liquid or gas in the bloodstream that can block blood vessels

Expectorant of blood from respiratory tract
