Document Summary
The ability to do work or transfer heat. Can be transferred by contact, like collisions. Heat/thermal: a type of ke created by a change in temperature. Electrical: a type of ke associated with the flow of electrical charge. Light/radiant: ke associated with energy transitions in an atom. Potential: energy associated with position or composition. Chemical: energy stored in the bonds of compounds, the. Units of measurement positions of electrons and the nuclei. Nuclear: pe in the nucleus of atoms. 1j is the amount of energy required to move 1kg at a. 1 cal is the amount of energy needed to change the. 1 calorie=4. 184j temperature of 1g of water by 1 . Total energy in the universe is constant. Value of internal energy of a system. **internal energy of a system is independent of the path by which the object takes to achieve that state. Only depends on the internal energy (the initial and present states of the energy system)
