Newton'sFirstLawstates 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 as stated below applies to a wide range of physical phenomena, but it is not a fundamental principle like theConservation Laws. It is applicable only if theforceis the net external force. It does not apply directly to situations where the mass is changing, either from loss or gain of material, or because the object is traveling close to the speed of light where relativistic effects must be included. It does not apply directly on the very small scale of the atom where quantum mechanics must be used.

First Law of motion :- This states the body remains at the state of rest or motion unless is has been acted by an external force ! If there was no friction the ball would keep rolling on the floor !

Second Law of motion :- This brings about a relation between Force , mass and acceleration given by F=ma , and is the source of whole mechanics studies

Third Law Of Motion :- Every action has an equal and opposite reaction. !

Third law every reaction has equal and opposite reaction
