25
projectile motion
height, angle and speed of release
26
force summation
the correct timing and sequencing of body segments and muscles through a range of motion.
27
speed
How quickly an object covers distance. | Speed = distance/time
28
velocity
how quickly an object is changing its position, relative to its starting position. Velocity = displacement/time
29
angular momentum
measures an objects resistance to change its state of rotation, relates to newtons 1st law.
30
Newtons 1st law
inertia - A body will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
31
newton's 2nd law
force and acceleration - A force applied to an object will produce a change in motion (acceleration) in the direction of the applied force that is directly proportional to the size of the force.
32
newton's 3rd law
every action has an equal and opposite reaction
33
distance
how far youve travelled
34
displacement
the change in position of an object (A to B)
35
acceleration
increase, decrease or change in rate
36
mechanical advantage
enables us to move a great resistance w/ a minimal force.
37
axis
turning point of a lever
38
force
point where force is applied
39
resistance
weight of whatever a person is trying to move
40
First class lever
at either end is force and resistance, axis in middle | eg see saw
41
Second class lever
resistance situated between axis and force | eg. wheelbarrow
42
third class lever
resistance is weight of an object, force in between axis and resistance. eg. throwing a ball
43
equilibrium
balance of forces in opposition to each other
44
stability
a body resists changing it equilibrium
45
balance
controlling the state of equilibrium
46
centre of gravity
central point of an object
47
base of support
area of an object that is in contact with the surface supporting it
48
line of gravity
imaginary line which passes through the centre of gravity and continues down into the centre of the object BOS.
49
qualitative analysis
observation of the quality og human movement to provide ways to improve performance.
50
Observation
skill is recorded or measured through watching or recording
51
evaluation
compare pictures or body composition in each phase of movement
52
error correction
once strengths and weaknesses are identified, analyst can use it to improve the athletes performance.
53
Individual constraints
internal factors such as physical constraints, level of fitness, body shape etc.
54
task constraints
task factors eg. equipment, rules of game
55
environmental constraints
external factors - coaching, peer behaviour, weather.
56
direct approach
highly structured, coach makes most decisions about practice, feedback at all stages. POS - effective, master techniques NEG - repetitive, dependent on coach
57
constraints based approach
learner takes inquiry approach to independently develop their skills, strategies and tactics. of a game. often includes modified equipment. POS - specific to game, involves learner decision making, engaging NEG - difficult with large groups, harder for coaches to implement
58
Cognitive stage of learning
- making many errors - unable to correct error in technique without instruction - blocked practice and direct approach is best suited
59
associative stage of learning
- learner tries to refine the skill - mastered basics - can identify errors and how to correct them - random practice and constraints based approach
60
autonomous stage of learning
- highly skilled and little to no errors - complete skills with no thought - read cues in game - random, distributed practice and open environment are best
61
factors on skill development
sociocultural factors - family, time, peers, location, community, gender, Socio-economic status
62
intrinsic feedback
sensory info the learner gets directly from skill execution (internal)
63
augmented feedback
info about performance from an external source
64
knowledge of performance
feedback regarding how a skill is performed, assessing performance on the basis of process and skill technique
65
knowledge of results
info about outcome of skill performance, about relative success or failure in regard to intended goals of the movement skill.
66
massed practice
little or no rest between repeat performances of a skill
67
distributed practice
broken up into smaller practice intervals with rest periods
68
blocked practice
each skill component is practiced repetitively as an independent block
69
serial practice
in between blocked and random, rehearsing different skills in a fixed and predictable sequence.
70
random practice
rehearsing a number of different skills in unpredictable sequences
