Basic Concepts of Biomechanics
1 Newtons 3 Laws of Motions
1.1 1st Law
1.1.1 An object remains in a state of rest unless acted upon by an external force
1.2 2nd Law
1.2.1 When a force acts upon an object the motion experience is proportionate to the size of the force and in the direction applied
1.3 3rd Law
1.3.1 For every action there is an equal and opposite reaction
2 Types of Motion
2.1 Linear
2.1.1 When an object moves in a straight line with all its parts moving the same
2.2 Angular
2.2.1 When a body or part of body moves in a circle about a point
2.3 General
2.3.1 General motion is a combo of both angular and linear motion
3 Centre Of Mass
3.1 An imaginary point where all of your points of your body are equal
4 Stability
4.1 Stability is dependent on the center of mass being directly above the base of support
5 Force
5.1 5) Can be used to change the shape of a body
5.2 1) Can be used to make a body move at rest
5.3 3) Can be used to make a moving body slow down or stop moving
5.4 4) Can be used to make a moving body accelerate
5.5 2) Can be used to make a moving body change direction
5.6 The force that acts must be large enough to overcome the inertria of the body
5.7 The Effect of a force (SAD)
5.7.1 Depends on the SIZE of the force (weight) The force that muscle can exert is governed by the size and number of muscle fibres
5.7.1.1 Depends on where you APPLY the force, if its place off the centre of mass then angular motion will be produced
5.7.1.1.1 Depends on the DIRECTION of the force. If applied through the centre of mass then the body will move in the same direction as the force
