Energy can be transferred (moved from one place to another) and transformed (changed from one kind to another), but the overall amount of energy is always conserved, i.e. it remains constant.
Kinetic, potential, gravitational, and electrical energy are among the various forms of energy.
Examples of energy converters:
Electrical Energy Mechanical Energy
Electrical Energy Heat Energy
Electrical Energy Heat Energy + Light Energy
Electrical Energy Kinetic Energy Sound Energy
Chemical Energy Heat Energy Kinetic Energy or Mechanical Energy
Chemical Energy Electrical Energy
Chemical Energy Heat Energy
Chemical Energy Electrical Energy Light and Heat Energy.
