And even more amazing...how does nature know exactly how to
CHANGE how much energy is lost when viewed in a different frame?

In the ideal case of two equal masses colliding linearly
stationary and one is moving whereby they stick together after theleads to
collision (totally inelastic), the conservation of momentum
the conclusion that half the kinetic energy is lost toother forms.
Of course, in the real world, one has sound, deflection ofmaterials,
friction at least that will convert the energy to other forms.frictionless, rigid
But what does this really say? What do the "ideal" conditions mean?
Why, regardless of the masses is exactly half of the kinetic energy
lost. When we say "ideal" conditions to we mean
objects in an airless world?could make the
Can someone help make some sense out of this? I wish I
question more clear so perhaps it is my lack of clarity about the
situation that is the cause of the question. Any help in clarifying
this issue would be appreciated. David Abineri
