Q

What are the properties of water?

A

It is non-compressible, & is much denser than air, therefore, has greater viscosity.

Q

Water is very close to the density of a human body what does this mean for the energy cost towards gravity?

Q

How does Drag increase?

A

Current & speed of the object due to the separation of flow from object to turbulent flow.

17
Q

What are the types of swimming?

A

Prolonged, Sustained, and burst.

18
Q

Which type of swimming is the intermediate type that uses both anaerobic and aerobic respiration?

A

Prolonged swimming.

19
Q

Which swimming is used for long journeys (migration)?

A

Sustained Swimming

20
Q

Which type of swimming would a fish use for escaping predators, chasing prey, and swimming against currents?

A

Burst swimming

21
Q

Describe sustained swimming.

A

Respiration: Aerobic, Speed: Slow, Muscle type: Red or uses slow oxidative muscle power, Fatigue: Slow. Used to travel long distances and forage.
