    This is so amazing! You explain so beautifully and its such a selfless giving of your time and expertise. My daughter is only in grade 7 but I found myself reliving my own high school science watching your videos. Following you so that one day I can come back here to help my daughter.

      Thank you so much Nelia... It is such a pleasure. I'll try to produce material for grades 10 and 11 as well. I hope it will help your daughter to obtain the good results she hopes for.

    Sir I dont understand why for questions where one of the balls is thrown one second later the time is t-1 why is it not t+1? since there is a 1 second delay🤔

    • @Gioviljoen
      @Gioviljoen 6 місяців тому

      It’s beacause if a ball is thrown at 0 s and then they say the other is thrown 1 s later, this meant -1 if it where thrown 1 be earlier it would be + 1

    • @Gioviljoen
      @Gioviljoen 6 місяців тому

      The reason is that we shouldn’t look at the time delay the formula acts like an additive inverse if it’s +1 it becomes -1 and if -1 it becomes +1

    Good day sir , hope you well... Sir im a bit confused with the signs and directions because my teacher said when an object is going upward then we take upward motion as positive but our gravitational acceleration will be negative and when an object is dropped downwards then all our equations will be postive but you doing it vice versa

    • @MlungisiNkosi
      @MlungisiNkosi  2 роки тому +1

      The direction of motion you assume is your choice. There’s no rule about that… Please make sure once you’ve chosen a direction, that you stick to it.

    • @cassie3289
      @cassie3289 2 роки тому +6

      @@tumelokhosa2434 Hi. No. Gravitational acceleration always moves downwards or as my teacher likes to say, it's always considered a "downward force". If you choose upwards as positive then all your forces that go downwards are considered to be negative. If you choose your downward forces to be positive then all upward forces are negative. Hope this helps :-)
