Biomechanics

definition of the following terms:

Define linear motion: Movement that is along a straight or curved line (no rotation) and all body parts move in the same direction at the same speed 

Define angular motion: Where all the parts of a body move through a rotational pathway through the same angle in the same direction at the same time

Define general motion: combination of linear and angular motion

Define projectile motion: Anything that is propelled through the air or water amn affect by only the forces of gravity and air resistance

application of linear motion to sport in relation to:

  • speed - Measure of distance object travels per unit of time, a representation of how quickly something cover a given distance

  • velocity -

  • acceleration -

application of projectile motion to sport in relation to:

  • optimal projection

  • parabolic trajectory

  • release of projectiles

    • angle

    • velocity

    • height

definition of the principle of balance and how it applies to sport in relation to:

  • base of support

  • height of the centre of gravity

  • line of the centre of gravity

  • mass

  • static balance
