Question

a family is moving from pennsylvania to connecticut during the summer. as the moving van burns gasoline, its engine converts chemical energy from the gasoline to potential energy of the truck moving.

Explanation:

The problem is about energy conversion in a moving van's engine. When gasoline (chemical energy) is burned, the engine converts it to mechanical energy (the energy of the truck moving, which is kinetic, not potential). So the second dropdown should be corrected from "potential" to "mechanical" (or "kinetic") as the energy of a moving object is kinetic/mechanical.

Answer:

For the second dropdown, the correct term should be "mechanical" (or "kinetic") instead of "potential" since the truck's movement involves kinetic (mechanical) energy from the conversion of gasoline's chemical energy.
