2.    Newton’s second Law

“if the force or resultant of force working on an object is zero,then  the object will experience an acceleration in the same direction with the resultant force”.  

3.    Newtons’s Third Law

“for every action there will always be reaction in the same line. The magnitude of direction force is the same as that of the action, but in the opposite direction.
