Question 30

This deals with the manner in which adjoining joint surfaces move in relation to each other? ( in the same or opposite directions)

Answer 30

Arthrokinematics

Question 31

Question 32

An object at rest, tends to stay at rest; whike an object in motion tends to stay in motion?

Answer 32

Newtons 1st law: law of inertia

Question 33

1) the amount of acceleration depends on the strength of the force applied to an object 2) acceleration is inversely proportional to the mass of an object

Answer 33

Newtons 2nd law: law of acceleration

Question 34

For every action there is an equak & opposite reaction
