Given:
Gasoline, wood, water behind a dam, and a boulder on the edge of a cliff all represent some form of potential energy.
To find:
What form of potential energy do gasoline and wood have in common.
Step-by-step explanation:
Gasoline and wood contains chemical energy. Thus when gasoline and wood is burnt the chemical energy stored gets converted to thermal energy. This thermal energy is stored in form of heat.
Conclusion:
Thus the forms of potential energy common to both wood and gasoline is:
Chemical potential energy.
