    how did you get -9.8 for the acceleration?
    please help, thanks

    • @MrSmithsPhysicsonline
      @MrSmithsPhysicsonline  5 років тому +74

      That's the acceleration due to gravity. Using sign convention and taking upwards as positive, that means that acceleration due to gravity (always taken as downwards) must be -9.8ms-2.

    • @deepikasaxena2287
      @deepikasaxena2287 4 роки тому +15

      @Mariyam Jahangir Hey! 9.8 ms is the value of Earth's gravity. As the objects motion was upwards, the gravity was opposing it. So was used with negative sign .

    • @MrSmithsPhysicsonline
      @MrSmithsPhysicsonline  4 роки тому +12

      @Mariyam Jahangir when you drop an object on Earth, it accelerates towards the ground at 9.8ms⁻² (ignoring the effects of air resistance). As for the negative sign, that's called 'sign convention' - deciding which direction is positive and which is negative. I take upwards to be the positive direction. Since objects accelerate downwards (the negative direction), acceleration due to gravity is taken as -9.8ms⁻²

    Why would people dislike the truth about the Equations of motion everything is perfect
    *its slow pace to not fall behind
    *simple and going through each step
    *perfect illustration
    i can't see why people disliked this?

      There is a video called 'Velocity-time graphs' - is that any use to you? If you tell me what areas the video would need to cover, it's something which I'm sure I could do at some time because it wouldn't take too much work.

    • @MrSmithsPhysicsonline
      @MrSmithsPhysicsonline  4 роки тому

      The full question is “a ball is thrown vertically upwards from the edge of a cliff as shown on the diagram” on the diagram shows the cliff being 33 m tall and the ball being thrown at 4 ms-1 “the effects of friction can be ignored” a) “what is the height of the ball above sea level 2 seconds after being thrown?” Thanks for the help
