Which are two forms of potential energy a. chemical energy and gravitational energy b. gravitational energy and thermal energy c. gravitational energy and sound energy d. thermal energy and seismic energy

A

Chemical energy is a type of potential energy because it is not kinetic energy, unlike sound, thermal, and seismic energy. Similarly gravitational energy isn't related to how fast an object moves but instead how far up it is from the ground.

i would say b

explanation:

but i think i would need more information than that
