|---|---|---|---|---|---|
| Buoyancy . | Archimedesʼ principle states that there is an upward force on the body when immersed in water equal to the amount of water that has been displaced by the body
🗑
|
||||
| Buoyancy The ability to | float in water results from the body possessing a specific gravity less than that of water.
🗑
|
||||
| Hydrostatic pressure | Water exerts pressure that is perpendicular to the body and increases in proportion with the depth of immersion.
🗑
|
||||
| Resistance | Water molecules tend to attract to each other and provide resistance to movement of the body in the water.
🗑
|
||||
| Resistance by water | increases in proportion to speed of motion.
🗑
|
||||
| Specific Gravity | The computation for the specific gravity of water is equal to 1.
🗑
|
||||
| The human body varies based on size and somatotype but typically has a specific gravity of | less than 1 (average .974). Therefore, a person will generally float when fully submerged in water.
🗑
|
||||
| The specific heat is the | measure of the ability of a fluid to store heat.
🗑
|
||||
| specific heat is calculated as | the amount of thermal energy required to increase the fluidʼs temperature by one unit.
🗑
|
||||
| Water can store four times the heat | as compared to air.
🗑
|
||||
| Waterʼs thermal conductivity is approximately | 25 times faster than air at the same temperature.
🗑
|
||||
| The total drag force | is comprised of profile drag, wave drag, and surface drag forces.
🗑
|
||||
| total drag force is a | hydromechanic force exerted on a person submerged in water that normally opposes the direction of the bodyʼs motion.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
