    Hey, I've watched so many of your videos and they helped me with so much with my physics exams, you really put it in a term that's easy to understand when compared to the revision guide. You're amazing, thankyou for all of these videos!

    Great video!
    It is interesting (and weird) how often 2π appears in the calculations. That happens because π is calculated from diameter instead of radius, which is kinda silly since all calculations of the kind uses radius.
    I bet it would be easier for calculations if we all used τ (tau) instead. τ = 2π

    • @DoodleScience
      @DoodleScience  9 ปีที่แล้ว +2

      +Alexandre Pereira (Alenonimo) We probably would be a lot better off using tau! But then again convention makes explaining things to other people a lot easier :)

    • @ws04
      @ws04 9 ปีที่แล้ว +2

      +Alexandre Pereira (Alenonimo) lol then why would it not be weird that tau appeared so often in the calculations?

    • @alenonimo
      @alenonimo 4 ปีที่แล้ว

      @P T Using diameter instead of radius is kind of janky and makes it a bit harder to use with other equations. That's why tau is better than pi. It gets rid of all those 2π we keep seeing around.

    Why is there an acceleration if the speed is constant? i understand that there is a change in direction because of the velocity but the magnitude of the velocity is constant therefore there is no acceleration.How did u came up with the acceleration pls explain further. thanks

    • @leobarr1939
      @leobarr1939 8 ปีที่แล้ว

      acceleration is change in velocity. velocity is speed and direction. the direction is constantly changing, so velocity is constantly changing, so it is accelerating. hope you found this out before now but maybe a future person will want to see this.

  • @YAHOOOOOO5
    @YAHOOOOOO5 9 ปีที่แล้ว

    what causes the object to accelerate? is it the force? if it is the force then why is the formula for acceleration=v^2/r ?

    • @DoodleScience
      @DoodleScience  9 ปีที่แล้ว

      +YAHOO The force acting towards the centre of the circle causes the body to undergo circular motion the formula for the force is F=mv^2/r. To answer your other question, velocity is a vector quantity which has both magnitude and direction, so if the direction changes the velocity changes. Since the acceleration is the rate of change of velocity, there is also an acceleration. Hope that helped! :)

  • @noname-zc9tl

    If the vertical circle was a Ferris wheel or something where the person is not upside down, would the normal force at the top be acting upwards from the seat?

    why is the normal reaction force acting downwards at the top in ur last example?? shouldn’t it act upwards??

    • @DoodleScience
      @DoodleScience  6 ปีที่แล้ว

      mom42526 wyw It's because at the top the pilot will be upside down but still sat on his seat so the normal will act downwards from this frame. Hope that helps!

      m is the mass of the object which is being affected by the centripetal force.
