The law of conservation of energy states that the total amount of energy in any isolated physical system remains unchanged over time, although this energy can be transformed into another form of energy, in this case we initially have gravitational potential energy (due to height and gravity) and then it is transformed into kinetic energy (due to the movement)
where m is the mass , g the gravity and h the height
assuming that there is no air resistance the energy is conserved
the energy it has right before it hits the ground is 19.6 J

Nope. Energy is directly proportional to frequency. and when you calculate energy, you multiply frequency with a constant number called "Planck's Constant"
