Q

Chemical energy

A

Is stored energy (potential energy.) It is stored in the bonds between atoms and molecules. Chemical energy is what holds the atoms in a molecule together. It also is what holds the molecule in a substance together.

Q

Electrical energy

A

Is a type of kinetic energy caused by moving electric charges. The amount of energy depends on the speed of the charges/ The faster they move, the more electrical energy they carry. Energy carried by electrical currents (wall sockets.)
