Unit 12 - 7 Principles of Biomechanics

Question 1

Statics

Answer 1

branch of mechanics that deals with objects or bodies in a state of constant, unchanging motion

Question 2

dynamics

Answer 2

system is one that experiences a change in the rate at which it is moving as a result of forces applied to it

Question 3

stability

Answer 3

The greater the mass, the lower the centre of mass to the base of support, the larger the base of support, and the closer the centre of mass is positioned to the base of support, the more stability increases

Question 4

production of max force

Answer 4

requires the use of all possible joint movements that contribute to the task’s objective

Question 5

production of max effort

Answer 5

requires the use of joints in order—from largest to smallest

Question 6

Impulse-momentum relationship

Answer 6

The greater the applied impulse, the greater the increase in velocity

Question 7

direction of application of applied force

Answer 7

Movement usually occurs in the direction opposite that of the applied force

Question 8

angular motion

Answer 8

is produced by the application of a force acting at some distance from an axis; that is, by torque

Question 9

angular momentum

Answer 9

is constant when an individual or object is free in the air
