Question: If air resistance is zero, the sum of potential and kinetic energy of a freely falling body will
Show that the sum of kinetic energy and potential energy(i.e., total mechanical energy) is always conserved in the case of freely falling body under gravity (with air resistance neglected) from a height h by finding it when (i) the body is at the top, (ii) the body has fallen a distance x, (iii) the body has reached the ground.
In a freely falling body, the interchange of potential to kinetic energy takes place _______.
