definitions & terminologies
1
mechanics
the science that studies the influence of
force
on bodies
biomechanics
application of mechanics to biological systems
4
define force
is a push or a pull that produces displacement
-have
magnitude
& direction
point of application
line of action
2
motion
principle of an object moving
therefore motion is the change in position over time
kinematic variables that describe motion
type
location
direction
magnitude
velocity or acceleration
3
types of motion
linear/translatory motion
is the motion along a straight line
can be a straight or curved line
angular/rotary motion
is rotation around an axis
(center of rotaion -CoR) in a curved path
5
explain point of application
is the exact location at which a force is applied
for muscles its attachment to bone lever
6
classify forces
joint rxn force
-amnt of force 2 bones apply to each other
fluid resistance
-force of the water against the body
inertial force
eg: force of inertia keeping ankle swinging forward in running
(newton's 1st law)
friction
-amnt of force created when 1 surface moves over another
ground rxn force
-resistance that the ground applies to the body
elastic force
-material changes length when a force is applied to it
eg: trampoline
7
differentiate
concurrent,co-planer,co-linear forces
8
describe composition
& resolution of forces
9
identify angle of pulls of muscle
