Biomechanics

Where is the centre of mass of a high jumper during the flight phase over the bar using the Fosbury Flop?

• Above the body

• In the centre of the body

• Below the body

• It depends on the person

Regarding 2nd class levers, where is 1.load, 2.fulcrum and 3. effort in a sprinters lower leg during the sprint start from the blocks.

• 1.tibia 2.metacarpals 3. gastrocnemius

• 1.femur 2.patella 3.quadriceps

• 1.fibula 2.metacarpals 3. gastrocnemius

• 1.metacarpals 2.tibia 3. gastrocnemius

What does Angular kinematics look at?

• Angular kinematics looks at acceleration at an angle

• Angular kinematics looks at motion around an axis

• Angular kinematics looks at momentum and displacement

• Angular kinematics looks at motion in a specific direction

How many ways can a body rotate around an axis?

• 1

• 2

• 3

• 4

What is the Magnus Effect?

• the mathematical point around which the mass of a body

  or object is evenly distributed

• the force exerted on a rapidly spinning cylinder or sphere moving through air

• opposing forces causing an object making waves in a

  fluid

• a rotating body that continues to turn about its axis with constant angular momentum
