examples: 1st law- Bottle kept on the table will remain in same condition (Kept) until somebody apply force. in absence of all forces if a bottle is moving then it will remain moving with same motion until external force applied. This is called Inertia and the object which is considered under this observance is called inertial Object. So in above example Bottle is a inertial Object. 2nd Law: If a bottle is static or moving in absence of all force then it is considered as a inertial Object but if somebody apply a force and the condition (Static or Motion) is changed then it is called Force has been applied. hence in second law Force has been Defined. Which is mathematically, F= ma, where, m= Mass and a= Acceleration or Deceleration. 3rd Law: Whenever anyone slap somebody on face then slapper feels also some pain on his hand and the person whom he slapped feels pain on his face of-course. Its means both of them hurt or felt equal Force, doesn't matter who had slapped. the only deference is face is softer than the hand so its feels more pain but effect of force is same on face as well as on hand. in short every action has a equal and opposite reaction So if somebody will slap you next time then take it easy because your face has attacked on hand of slapper with same force equally opposite. Finally revenge has taken by your face. So why fight? ha ha ha.....Good Luck.
