A
newtons first law
2
Q
which one of newtons laws applies to dynamics
A
newtons second law
3
Q
what is newtons first law
A
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
4
Q
what is newtons third law
A
if object A exerts a force on object B, object B exerts an equal and opposite force on object A
5
Q
what is newtons second law
A
force = mass * acceleration (F=MA)
6
Q
what are the main conditions for newtons third law
A
-has the same magnitude
-opposite directions
-same type of force
-on different objects
7
