Q
Newtons 1 law
A
If the resultant force on a stationary object is 0 it will not move.
If the resultant force on a moving object is 0 it will move at same velocity.
9
Q
Newton 2 law
A
Acceleration of an object is directly proportional to the resultant force.
Acceleration is inversely proportional to mass.
