Force platform 1 of 29 What does Fx refer to? Medial/lateral (frontal) direction 2 of 29 What does Fy refer to? Sagittal plane 3 of 29 What does Fx refer to? Transverse plane 4 of 29 What is the maximum Fz force in walking? 1.25 bw 5 of 29 What are the peaks in Fz walking gait? Heel strike transient, before mid stance, before toe off 6 of 29 What is the max posterior force during walking gait? 0.25 bw 7 of 29 What is the maximal medial force during walking? 0.1 bw 8 of 29 What is the maximal Fz force during running? 5 bw 9 of 29 How does the magnitude of forces in running compare to running? Much bigger 10 of 29 How does the shape of GFR curves differ in walking and running? Running is more spaced out 11 of 29 What is the maximum posterior force in running? 0.5 bw 12 of 29 What is the maximal medial force in running? 0.25 bw 13 of 29 Is there a heel strike in fore foot strikers? No 14 of 29 In what order during both running and walking is the retarding phase and propulsion phase? 1. Retarding phase 2. propulsion phase in both 15 of 29 On initial contact, what direction is the force in walking? Anterior movement 16 of 29 On initial contact, what direction is the force in running? Posterior movement 17 of 29 If there is an equal retarding and propulsion phase, what is it called? Steady state 18 of 29 If the propulsion phase is larger than the retarding phase, what is the gait called? Propulsion gait 19 of 29 If there is a net deceleration because there is more anterior force than posterior, what type of gait is it? Slowing gait 20 of 29 What is represented by the area underneath a force time curve? Impulse and change in momentum 21 of 29 What equation represents the law of acceleration? F = (m2v2-m1v2)/t 22 of 29 What acts parallel to where 2 surfaces contact during the motion of one surface relative to another? Friction 23 of 29 What is frictional force dependant on? Normal reaction force (F) and coefficient of friction 24 of 29 What is the coefficient of static friction? When two objects are not moving relative to one another 25 of 29 What is the coefficient of dynamic friction? When 2 objects are moving relative to one another 26 of 29 What is usually smaller, coefficient of static friction or dynamic friction? Dynamic friction 27 of 29 The coefficient of static friction is usually a... Small number 28 of 29 Friction opposes just the start of movement? False 29 of 29
