    In the first practice question at the end of the video, where did the 10 come from? How do we know the value of 'g'?

    • @shrithikkothari8220
      @shrithikkothari8220 Рік тому +3

      G stands for acceleration of gravity, and its speed is generally taken as 10 m/s for convenient calculation although it is accepted that it's actually 9.8 m/s. You can assume it to be 10m/s when not explicitly stated otherwise.

      If displacement is zero, work done is also zero.
