BIOMECHANICAL CONCEPTS Flashcards
BIOMECHANICS - DEFINITION
A field that combines the disciplines of biology and engineering mechanisms and utilises the tools of physics, mathematics and engineering to quantitatively describe the properties of biological materials
KINESIOLOGY - DEFINITION
The scientific study of human movement. Kinesiology addresses physiological, biomechanics and psychological dynamic principles and mechanisms of movement
ARTHROKINETICS - DEFINITION
A field that combines the disciplines of biology and engineering mechanics and utilises the tools of physics, mathematics and engineering to quantitatively describe the properties of movement of the joints

WHAT IS FORCE?
Force is a push or a pull, with an unequal force allowing an object/limb to move as a result
6 TYPES OF FORCE
Tension
Compression
Bending
Shearing
Torsion
Combined loading
NEWTON’S 1ST LAW OF MOTION
Football being kicked, will remain stationary until it is kicked and will continue at the same speed until it meets another force or resistance
NEWTON’S 2ND LAW OF ACCELERATION
Pulling something: you need a force to make something move and the heavier the mass the greater the force you need to move it. The bigger you are the more energy needed to jump to the same height
