    Because moon is rotating with great velocity so it escapes before falling down

    Thanks for the session sir😄 short and educative☺
    🔴HOMEWORK
    there can be following reasons why moon is not colliding with the earth-
    1) the moon is moving around earth with high speed
    2) it is moving in a angular direction with high speed but due to gravity of earth it changes its path into curve
    3) the orbit of moon allows it to rotate in a fixed path
    4) centripetal force

    Thank you sir for this wonderful explanation 😀😊😇
    Homework Answer:
    The moon does not fall towards Earth due to its high velocity. The high velocity of the moon keeps it always escaping the Earth’s surface due to which moon keeps orbiting and never falls towards Earth.

    Homework. 1.centripetal force and moon is moving greater force.2. both have force of attraction between them

    It was a very splendid session
    Sir I have a doubt 😊😊
    Why acceleration of a body is 0 when it is with constant velocity
    Sir plz tell

    • @Mineplays12
      @Mineplays12 ปีที่แล้ว +1

      Constant velocity means that an object maintains the same speed and direction over a given time interval. It is characterized by zero acceleration, which means that there is no change in velocity with time. Mathematically, acceleration is the first time derivative of velocity, so if velocity is constant, acceleration is zero.

    Thanku soo much sir❤❤ for this concept bite session..i have already saw the session of numerical this helped alot in revision. Thanks one again❤❤❤
    The moon does not fall on the earth because of the centripetal force.
