Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion.
Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. Thesecond law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
Newtions 3 law An objest in motion stayes in motion unless acted upon by an equal and opposite force.
