Newton's 2nd Law of Motion

                Newton's 2nd Law of Motion

                                 


Statement: 
                      "when a force is applied on a body it produce acceleration in it,which is directly proportional to the applied force and inversely proportional to mass of body"

Explanation:
                          Suppose force (F) is applied on a body of mass (m) due to which acceleration
(a) is produce in it.

                                   According to Newton 2nd Law           

                                                   a ∝ F...............(1)
                                                   a ∝ 1
                                                         一..............(2)
                                                         m
                                                  combining equ (1) and (2)
                                                  a ∝ F
                                                        ー
                                                         m
                                             a (constant) F
                                                                ー
                                                                m

                                            hare,constant = 1 so
                                                               a=F
                                                                  ー
                                                                   m

                                                   F=ma proved.

                


This is the mathematical form of newton 2nd law of motion.
