  • 1

    Propulsive efficiency is a measure of the ability of a swimmer to fully utilise which physical law?

    Newton's Third Law (action-reaction)

  • 2

    Most of the propulsion in swimming comes from the presence of two forces. They are:

    drag and lift

  • 3

    Bernoullis's theorem is best described as:

    changes in fluid flow velocity is associated with changes in fluid pressure

  • 4

    Research has shown that increases in crawl-stroke swimming speeds are associated with:

    decreases in both ventral and dorsal hand pressures

  • 5

    Lift forces around an aerofoil (such as the hand in swimming) can be best explained by which of the following mechanisms:

    the angle of the aerofoil (or hand) causes a turning of the oncoming fluid and change in fluid direction must occur with an opposite movement of the aerofoil, according to Newton's Second Law (i.e. action-reaction or conservation of momentum)
