What is kinetic energy?
The energy of a system’s particles in motion
What is potential energy?
The energy of a system based on its’ position
What is thermal energy?
The energy contained in a system that affects its temperature.
What is Gibbs Free Energy?
The max amt of potential energy in a system that can be released to the surroundings
