Types of swimming Flashcards
What are the types of lift?
Static and Dynamic lift
What does static lift include?
Swim bladder & Lipids/oils
What does dynamic lift include?
Pectoral fins rotation and their hydrofoil shape facilitate dynamic lift
What counters gravity?
Lift
What is lift?
Lift counters gravity.
What is gravity?
The magnetic pull from earth’s forces.
What counters drag?
Thrust
What is thrust?
It propels an object forward.
What is drag?
Friction produces by an object passing through a medium.
What are the properties of water?
It is non-compressible, & is much denser than air, therefore, has greater viscosity.
What property of water allows thrust to be easily done?
Non-compressible component of water.
Water is very close to the density of a human body what does this mean for the energy cost towards gravity?
Fishes extend little to no energy to resist gravity.
All fishes swim (T/F)
False
All fishes are good and fast swimmers (T/F)
False
Which is most efficient? Swimming or Walking?
Swimming is the most efficient by 7 times.
