Laws of Motion for IIT-JEE can be very interesting subject if the concepts get clear. Laws of motions are something which we can actually observe in our daily lives.
Newton gave three laws of motion and thus they are also called Newton's 3 laws of motion. These laws deals with the various applications of forces of action and reaction and their impact on motion of a body.
Once you start taking interest in these laws, you will start thinking about the world from a broader perspective (from a physics perspective).
