same height: 04 Initial KE + Initial GPE = Final KE + Final GPE -> 0 + mgho = 0 + mgh1 1) Why does initial kinetic energy equal 0 in the above expression? 6 86 2) Why does the final kinetic energy equal 0 in the above expression? However, you know from experience that even a very good bouncy ball will always bounce a little bit lower than the height from which it was dropped. This means that mechanical energy is not quite conserved. 10 3) Mechanical energy refers to kinetic energy + potential energy. What are some forms of energy that are not included in mechanical energy
