illustrate energy transformation as well as the conservation of momentum.
the explosives up requires conversion of chemical energy to
kinetic energy. The kinetic energy is used to overcome gravity and
is converted to potential energy in the process. During the explosion,
chemical energy is converted to mostly light, heat and
sound. The symmetry the fragments display is a consequence of the conservation
of momentum. The sum of the momenta before and after explosion is
the projectiles follow an inverted parabola.
to the "Big Bang Model" our universe may be viewed as a remnant of
a spectacular and mysterious firework that took place
about 15 billion years ago.
