Inertia against gravity...

[iacob alex]

    ...is based on the simple fact,that gravity has no inertia for a natural,vertical free fall.

       For a different trajectory of a gravity fall (let's say one curvilinear...),we "meet" inertia.

       All that I made,was to settle,compare  a  vertical free fall,with a rotary free fall.

       Can it help this topic?

   ...performs,everytime when a body falls on a different trajectory than the vertical line : the gravity must do a greater work,than on the vertical line.

      The reverse of a
vertical free fall,can be a jump-up motion.
      So,making a balance,correlation between a vertical free fall in gravity,and a fall on a different trajectory,but amid same levels,we can mesure a kinetic energy difference.

      The next idea is to use it.

.....or more precisely rotational inertia suggestion , as an extremely strong "wind" something alike :

When we like to wonder...it can be a seed to understand.

hi,
that link atwood.html on msu is 404, is there any substitute?

.....let's try as a substitute , at :

     Here , to store energy due to gravity unbalance , as much as possible is a main point for a massive pulley.
