1. deflection - answerdeflection: a turning aside or off course
b b b b b b b b b




Look at these : b b b




Which properties are important in deflecting force away from the body
b b b b b b b b b b




• Hard
b




• Rounded

• Smooth
b




• Ridges

2. dissipation -
b b




answerdissipation: to cause to spread thin or scatter and gradually vanish
b b b b b b b b b b b b




• Disperse focal force over a larger surface

3. deformation - answerdeformation: alteration of form or shape
b b b b b b b b b




• Change in shape or structure - cantilever pads
b b b b b b b b




• May blow apart @ high force - bike helmet
b b b b b b b b b




4. absorption -
b b




answerabsorption: to receive without recoil or echo (Merriam Webster on-

line dictionary)
b




Materials:

-Felt

-Foam (open cell or closed cell)
b b b b b




- Air
b




- Fluid
b




*Increased Density = greater resistance @ high force (denser foam will have gr

eater protective qualities with greater forces)
b b b b b




*Decreased Density = more absorption @ lower force
b b b b b b b




Absorption materials : felt - answer• Made from matted wool fibers

• Less tendency to shift or move over skin
b b b b b b b b




• Absorbs fluids (sweat, blood, etc)
b b b b b




- Heavy when wet
b b b




• Not very resilient
b b b




Must be replaced daily!
b b b




Absorption materials: foam (open cell) - answer- open cell
b b b b b b b b




Like sponge
b




Low resilience- doesn't bounce back
b b b b




Used to pad bony prominences
b b b b




Used to protect skin under hard edges of protective equipment (comfort)
b b b b b b b b b b




Decreased Density = more absorption @ lower force
b b b b b b b




absorption materials: foam (closed cell) - answerClosed cell (air cant go out)
b b b b b b b b b b b




• Used primarily for protection
b b b b




-Air can't pass from one to another
b b b b b b




• High resilience-Material rebounds and returns to its original shape quickly
b b b b b b b b b b




- Offers less cushioning at low levels of impact
