absolute ref system |
relative to 0 standard position; non-connected limbs |
|
relative |
absolute measurement |
|
kinematics |
w/o regard to cause of forces;
simple stuff; position, displacement, velocity, acceleration |
|
kinetics |
consider force lead to motion;
force, momentum, torque |
|
law of cosines |
magnitude |
|
law of sines |
direction |
|
first law of |
inertia - stays constant until acted on;
iar |
|
second law of |
acceleration - force applied causes acceleration
iar |
|
third law of |
reaction - every action has equal and opposite reaction;
iar |
|
as mass gets greater what happens to inertia? |
it also increases |
|
as mass moves away from axis what happens to MOI> |
increases |
|
greater MOI means? |
greater transfer of force |
|
decreasing MOI means what about speed? |
increasing speed |
|
stiffness |
resistance to deformation; slope |
|
pliability |
ease of deformation |
|
ductility |
undergo strain before failure |
|
brittleness |
breaks w/ little deformation |
|
creep |
increase in strain over time |
