*_The Firing Squad Demo... It's Physics!_* 

Every day we have to make choices. Sometimes these can be life
changing. In the Firing Squad Demo the student you pick to be the
target, will have to choose between two dart guns to be shot with! 

One of the guns has a steel ball glued to the dart. Standing
approximately ten feet from the two loaded guns he or she will need to
think like a physicist to make the right choice. Both guns, being
essentially identical, push the two different-mass darts with the same
force. Which dart will they choose to be shot with? 

Here the distinction between the inertia property of mass and its
gravitational property is illustrated.
