A presentation for a NASA grant regarding Leonardo da Vinci's Armoured Car.  I speak of potential energy, kinetic energy, chemical energy, and the conservation of energy of the cannons of the machine.
<p>As an addendum, yes I do say "um" too much in this video.  Yes I do need to work on that.
</p><p>Thank you to Pam Maher, Administrative Aide to the Nevada Regional Educator Resource Center, for prompting me to take up this grant, and for recording this video.
