dynamics and statics

Question 1

which one of newtons laws applies to statics

Answer 1

newtons first law

Question 2

which one of newtons laws applies to dynamics

Answer 2

newtons second law

Question 3

what is newtons first law

Answer 3

an object will stay at rest or continue to move at a constant speed in the same direction unless acted upon by a resultant force

Question 4

what is newtons third law

Answer 4

if object A exerts a force on object B, object B exerts an equal and opposite force on object A

Question 5

what is newtons second law

Answer 5

force = mass * acceleration (F=MA)

Question 6

what are the main conditions for newtons third law

Answer 6

-has the same magnitude
-opposite directions
-same type of force
-on different objects

Question 7

what are the key steps to finding a resultant force

Answer 7

resolve the vector using trigonometry

Question 8

describe contact forces in terms of particles

Answer 8

when there are two contact forces each objects the electrons in the atoms are displaced which results in a force against the object.
