Cards in this deck (20)

  1. 11/ what are the two sides to bio-mechanics ?1 - Kinetics
    2- Kinematics
  2. 22/ what is KinematicsDescription of
    motion
    What? When?
  3. 33/ what is KineticsStudy of the
    underlying causes
    of motion
    How? Why?
  4. 44/ how many meters in an acre?4047
  5. 55/ whats the equation for working out how for a ball will roll?2TT x r
  6. 66/ what are the two types of analysis?• qualitative
    • quantitative
  7. 77/ what is qualitativewords
  8. 88/ what is quantitativenumbers.
  9. 99/ what are the steps to analyzing1. identify the objective of the skill
    2. identify key events in the motion
    3. select phases (whose beginning and end
    are defined by specific events)
    4. identify the objective of each phase
  10. 109/ continued5. analyse the motions in each phase (kinematics)
    6. apply your bio-mechanics knowledge to
    understand the motion, or suggest
    improvements (kinetics)
  11. 1110/ what are the 2 types of motion?1 - Translation (Linear Motion)
    2 - Rotation (Angular Motion)
  12. 1211/ what can translation be broken down into? (2)1 - Recti-linear motion
    2 - Curvi-linear motion
  13. 1312/ what are the key features of translation (2)1 - the orientation of the body does not change
    2 - all points on the body move along identical,
    parallel paths
  14. 1413/ describe Recti-linear Motionthe common, parallel paths are straight lines
  15. 1514/ describe Curvi-linear Motionthe common, parallel paths are curved
  16. 1615/ what are the key features of rotation?• the orientation of the body changes
    • all points on the body move in concentric
    circles (about a shared axis)
  17. 1716/ However, pure translation or rotation are rare. Most human movements involve a combination of the two - called?general motion
  18. 1817/ when taking about change in position describe 1 - distance 2 - displacement1 - distance: length along the path taken
    2 - displacement: length ‘as the crow flies’
  19. 1918/ describe velocity?• the rate of change of position with time
  20. 2019/ whats the equation for velocity and what does this give use?velocity = displacement/change in time
    this gives us the average velocity over that time period
