what is newton's 1st law?
|
any object at rest, will remain at rest, and any object moving at a constant velocity, will remain moving at a constant velocity unless acted upon by an unbalanced force
|

|
what is newton's 2nd law?
|
acceleration depends on the object's mass and the net force acting upon the object
|
|
|
what is Newton's 3rd law?
|
if an object exerts force on an object, then the 2nd object exerts a force of equal strength in the opposite direction of 1st object

|
