1

What is bouyancy

The ability to disperse water to stay afloat

2

What is Archimedes' principle

An object that is immersed in water experiences an upward thrust equal to the weight of the water displaced

3

In water are upward or downward movements assisted

Upward movements

4

In water are upward or downward movements resisted

Downward movements

5

What is specific gravity

The measure of an objects density in g/cm3

6

What is the specific gravity of pure water at 4 C

1.00 g/cm

7

If an object has a specific gravity above 1.00 g/cm3 will it float or sink

Sink

8

If an object has a specific gravity below 1.00 g/cm3 will it float or sink

Float

9

What is a person with inflated lungs specific gravity

0.974 g/cm3

10

What is unity

Specific gravity of 1.00 g/cm3

11

What is the center of bouyancy

Reference point that only pertains to that segment of the body immersed in water

12

Is the rotary component of gravity compressive or distractive

Distractive

13

IS the rotary component of bouyancy compressive or distractive

Compressive

14

Where is the center of bouyancy applied

The center of mass of the object

15

What does changing the center of bouyancy do

Changes the MA of the exercise

16

What is hydrostatic pressure

Pressure exerted by the water on the immersed part

17

What is Pascal's Law

When an object is immersed in a fluid at rest the fluid will exert equal pressure on all surfaces of the object

18

What happens to hydrostatic pressure as you go deeper into the water

It increases

19

Is it easier or harder to breath the deeper you go

Harder because the hydrostatic pressure is higher

20

After 18 feet of diving while scuba diving do you have to do

Pause to let the body equalize the pressure

21

What movement speed causes less and more resistance in water

More: Moving faster
Less: Moving slower

22

What is viscosity

The degree to which a fluid resists flow

23

What is viscosity due to

The cohesive forces present between molecules

24

True or False:
The viscosity of water tends to resist movement in all directions

True

25

How does increasing the temperature effect viscosity

It decreases viscosity by relaxing the cohesive forces of the molecules

26

What temperature what is easier and harder for exercising

Easier: Warmer water
Harder: Colder water

27

What are the physiological effects of hydrotherapy (6)

1. Cleansing effects
2. Musculoskeletal effects
3. Cardiovascular effects
4. Respiratory effects
5. Renal effects
6. Psychological effects

28

What are the cleansing effects of hydrotherapy (5)

1. Treatment of open wounds
2. Pressure
3. Debriding agent
4. Cleansing agent
5. Can add products to water to improve cleansing power

29

How does the pressure effect cleansing

Softens and removes debris

30

How does a debriding agent effect cleansing

Removes endogenous agents
