Given:

The falling object

To find:

The dependence on the speed of the falling object

Explanation:

For an object falling freely, the total mechanical energy remains always constant. So, we can write, that the decrease in potential energy will be equal to the increase in the kinetic energy that is

[tex]\begin{gathered} \frac{1}{2}mv^2=mgh \\ v^2=2gh \end{gathered}[/tex]

Hence, the speed of the falling object does not depend on the mass it depends on the height difference.
