The coating on the head of a match is highly flammable. when it burns, it releases a great deal of energy.
however, before the match can burn, it must gain a small amount of energy from a spark. that spark is
typically produced by striking (rubbing) the match head against a rough surface. sketch and describe a
potential energy diagram that represents the striking and burning of the match. remember to label the
diagram with the energy changes that occur. your answer must include the potential energy diagram
and a written description. (note: you do not have to use actual energy values.) (5 points) 3 points for
the
graph and 2 points for written description
