Write the energy transformation equation for each situation

Fireworks explodes
An arrow is shot off a bow and flies through the air

What they are asking for are really not "equations" in the mathematial sense. The teacher should know that. What they probably want is an indication of the energy transformation process.

A fireworks explosion is a conversion of chemical energy to light, kinetic energyn and sound.

The heating of a paved driveway in sunlight is due to a conversion of solar light energy to heat energy and thermal motion in the driveway surface material.

See if you can figure out the others. The arrow one is easiest.
