  • Biomechanics
    • Newton's Laws
      • 1st Law - Law of Inertia
        • Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
      • 2nd Law - Law of Accelartion
        • Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
      • 3rd Law - Law of Reaction
        • For every action, there's an equal and opposite reaction.
    • Motions
      • Linear Motion
        • Linear motion is motion along a straight or curved line at the same distance, time and speed.
        • Examples: Curved Linear Motion - Shot Put. Straight Linear Motion - Rolling a ball in a straight line.
      • Angular Motion
        • An object that spins around it's axis of rotation.
        • Examples: A basketball spinning on your finger.
      • General Motion
        • This is a combination of angular and linear motion.
        • Cycling is an example of general motion, the wheels are in an angular motion, whereas the bike as a whole is moving forwards in a straight or curved line
    • Mass
      • Centre of Mass
        • However the centre of mass of a body is the point at which all of its mass could be considered to be concentrated.
      • The mass of a body is the amount of material of which it is made.
      • Stability
        • The state or quality of being stable.
        • Stability Depends on the following factors:        1) The position of athlete's centre of  mass           2) Position of athlete's line of gravity     3) Size of the athlete's area of support.
