energy | Definition, Types, Examples |

Energy, in physics, the capacity for doing may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various are, moreover, heat and work—, energy in the process of transfer from one body to another. After it has been transferred, energy is always designated according to its nature. Hence, heat transferred may become thermal energy, while work ...

EXPERIMENT 6: WORK AND ENERGY

EXPERIMENT 6: WORK AND ENERGY Objective: To validate the workenergy theorem and to study the conservation of energy principle. Theory: The workenergy theorem states that the net (total) work done on a system is equal to its increase in kinetic energy. You will determine the work done on a (nearly) frictionless cart and show that
