Momentum = Mass x Volume units used to measure momentum (kg.m/s) what is mass and what does it come before? Mass comes before Velocity what is velocity? Velocity: the speed of something in a given direction. Velocity = change in position divided by time taken. Eg. Football (AFL) how do you calculate angular momentum? Angular momentum = moment of inertia x angular velocity how can blanace be maintained? · COG within BOS · Width of BOS what is a motor unit made up of? made up of motor neurons and muscle fibres what is a motor unit? what is the all or nothing principle? Once the motor unit threshold is crossed all the motor units will contract or none at all. what is a direct and indirect injury? Direct injury: External force Indirect force: Sudden change in direction/intensity what is the use of heat on an injury and when should it be used? Heat: = After 48 hours = increase of blood flow, therefore more oxygen to increase rate of recovery what is the use of ice on an injury and when should it be used? Ice: used in 1 st 24 hours = decrease blood flow to swelling = increased rate of recovery. what are 3 ethical questions? Ethical Questions: · Is it unfair advantage? · Will I do more damage? · Will this increase performance? why do pitchers spin the ball? · Creates area of low pressure to the left = sucks the ball = spins. · Accuracy and speed increases. what is a first class lever? is a lever that has the fulcrum in-between the effort and the resistance. E.g. See Saw what is the second class lever? is a lever in which the resistance is located between the fulcrum and the effort. E.g. Wheelbarrow what is the third class lever? A third class lever: is a lever in which the effort is between the resistance and the fulcrum E.g. An arm Most common lever in the body: 3 rd class. define newton's law of inertia Newton’s law of Inertia: An object at rest will remain at rest unless acted on by an unbalanced force . An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. define newtons law of accerleration Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object). F=mass x acceler. what is ment by newtons law of action vs re-action? For every action there is an equal and opposite reaction. define Reciprocal Inhibition Reciprocal Inhibition Muscles work in pairs 1 contracts (agonist) the other relaxes (antagonist) Example: Biceps and Triceps what is the sliding filament theory? Sliding Filament Theory Myosin reaches out and grabs onto the actin, pulls the actin in, shortening the sarcomere. what is a sarcomere? Sarcomere H-zone decreases Z-line move closer, remain the same length. what are the 3 types of muscular contraction? - isotonic -isometric -isokinetic define isotonic contration and its two sub unit? isotonic- occurs when muscle length changes - concentric isotonic: the muscle shortens -eccentric isotonic: when the muscle lenghtens. define isometric contraction little if any change in muscle lenght during tension define isokenetic contraction max tension developed throught an entire range of movement (on fittness equitment) slow twitch muscle fibres explain they are also called red fibres aerobic endurance eg triathlons what are fast twitch muscle fibres they are white muscle fibres anaerobic for example spriting define anaerobic and aerobic. anaerobic: Relating to, involving, or requiring an absence of free oxygen aerobic: Relating to, involving, or requiring an absence of free oxygen what are the 3 types of joints? fibrous: no movement cartilaginous: slight movement synovial: freely movable what are the agnoist and antagonist muscles? agoist- the muscle primarily responsiple for producing movement antagonist- the muscle that relaxes as the agonist contracts. this muscle allows ease of movement. what are the 3 types of blood cells? red: carries oxgen and C02 to and from the body white: help to fight infection and disease platelets: help the create blood clotting what are the three types of blood vessels? veins: carry deoxygenated blood and have elastic walls arteries: carrie oxygenated blood and they have a pusle cappilaries: the site of gaseous exchange and are the smallest of blood vessels
