Question
Four balls are dropped from a platform, 20 meters high. One ball is 5k, the other is 10kg, then 20kg, and 40kg. Which ball will experience the GREATEST change in kinetic energy, from platform to ground?

The potential energy loss and kinetic energy gain is M g H, where H is the platform height.
Since the elevation change is the same for all, the heaviest one has the most PE loss and KE gain.
