Q

what is newtons second law of motion

A

the rate of change of acceleration to body is proportional to force applied

17
Q

what is newtons third law of motion

A

every action there is an equal and opposite reaction

18
Q

what is centre of gravity

A

the objects centre of balance or centre of weight

19
Q

what is stability

A

the bodys ability to remain in a state of balance

20
Q

what are the principles of the application of biomechanical knowledge

A

provide valid reasons for observed effects, diagnose problems with technique, justify changes in technique

21
Q

steps in biomechanical analysis

A

determine the objective of the skill, using observation, identifying movement patterns, divide the skill into skill phases, detecting errors, identifying starter mechanisms

22
Q

what is a motor skill

A

an activity that involves voluntary muscular movement with the correct degree of muscular control to complete a reasonably complect predetermined task

23
Q

what are sub routines

A

the order to perform a reasonably complex motor skill successfully, one needs to break down into components or parts

24
Q

what are skilled movements

A

when all subroutines of a skill are performed in the correct sequence and with correct timing

25
Q

what is a motor program

A

the whole plan

26
Q

what are fine motor skills

A

greater precision in the control of small muscles

27
Q

what are gross motor skills

A

movements that involve large parts of the body or whole body

28
Q

type of movement

A

discrete motor skills, continuous motor skills, serial skills

29
Q

what are discrete skills

A

that have a distinct beginning and end point

30
Q

what are continuous motor skills

A

movement sequence and usually are repetitive and do not have a clear beginning and end

31
Q

what are serial motor skills

A

a number of discrete skills performed in a movement sequence

32
Q

what are open skills

A

performed in unpredictable environments with constant changes

33
Q

what are closed skills

A

performed in more predictable environments with less changes

34
Q

what are the stages of learning

A

cognitive, associative, autonomous

35
Q

characteristics of the cognitive learner

A

many errors, poor timing, needs feedback constantly after each attempt

36
Q

characteristics of an associative learner

A

reduce the degree of errors, recognise errors themself, know how to do the skill not just what to do
