Thermodynamics is the study of energy transformations. In physics, energy is defined as the ability to do work(work=force/distance). Although we are unable to see or directly measure energy, we know that energy has the ability to make things happen. Two common forms of energy in chemistry are kenetic energy, the energy of motion, and potential energy, or stored energy.
Kinetic energy- energy of motion KE=1/2mv^2
Radiant energy- energy from the sun or solar energy
Thermal energy-energy associated with random motion of atoms and molecules
Chemical energy-energy stored within the structural units of chemical substances
Potential energy-energy stored or energy of position
