    Newton's fourth law of motion 😂😂:-
    Every book continues to be in state of rest and covered with dust until and unless internal and external exam appears and the speed of the page turning is directly proportional to the syllabus to be covered and tension in mind remain constant.

    thanks for the session sir😃 eagerly waiting for vasu sir's question-answer session😄
    🔴HOMEWORK-
    question-If iron sinks in water ,why does not the ships sink?
    answer- because the ships are structures made up of iron and steel with large hollow space filled with air....air have least density and thus is makes the ship to float on water....the same phenomenon is observed in glaciers of ice floating on water!!

      According to the third law of Newton, moon does attract Earth .But according to the second law of Newton, acceleration is inversely proportional to the mass of the object. Moon have smaller mass as compared to earth. So we do not see Earth moving towards the moon.
