Thanks a lot for your very nice message!
First, I am not a physicist.
Then you belong to the people I really want to see commenting. My posts are really targeting non physicists :D
Prof, I want to ask. My body weight is 78 Kg, when I jump from point A to point B with one step jump. Then I have been at point Z with energy 1/10 jump from point A to B. My question is ... how is this possible and can happen ....?
I am not too sure to follow, but this is a classical mechanics problem. You motion will be dictated by the ensemble of forces acting on your body (gravity, friction of air, etc.). The rest is to solve the equation and you will get your trajectory.
And don't be afraid of long comments: I write long posts :D
