slight ulnar dev

Question 18

OPP of trunk

Answer 18

midway bet flex & ext

Question 19

OPP of TMJ

Answer 19

slightly ajar

Question 20

2 subcategories of translatory motion

Answer 20

rectilinear (goes up & down)
curvilinear (travels along an curved path)

Question 21

3 laws of motion (Isaac newton)

Answer 21

Law of inertia
Law of Mass & acceleration
Law of Action & reaction

Question 22

what does Law of inertia state?

Answer 22

an obj at rest will remain at rest & an obj moving will keep moving unless an external force acts upon it

Question 23

What does Law of Mass & acceleration state?

Answer 23

F=ma

force is directly proportional to mass & acceleration

Question 24

what does Law of Action & reaction state

Answer 24

for every action, there is an equal and opposite reaction
