    00:08 Friction opposes motion
    06:29 Friction is the opposition to relative motion.
    12:18 Friction is affected by irregularities and adhesive forces.
    18:20 Wheels are considered one of the greatest inventions of mankind.
    23:24 Static friction is the resistance experienced between objects when they are at rest.
    28:52 Static friction is greater than sliding friction and rolling friction is the least.
    35:19 Friction works in opposite directions for the rear and front wheels of a cycle.
    41:11 Friction is a necessary evil in machines and everyday life.
    46:40 Friction: force affecting relative motion
    52:39 The output is between 3157.36 and 3159.44

    Sir why the friction was there in forward if the real wheel was moving forward?

    • @Chitra1693
      @Chitra1693 3 місяці тому

      wheel is pushing the ground backwards, that's why the wheel is moving foreword.

      Lubricant is a substance used to decrease friction either by making the object smooth or increasing moisture between them. This is used in cycle chains, old gates, rusty gears etc.

    does friction come into play only when two objects are in relative motion ? If so then why do we say we need friction to hold ,as there is no relative motion in this case.
