Work, energy, and power | AP®︎/College Physics 1 | Science | Khan Academy

Learn about kinetic and gravitational potential energy, understanding that a single object can only have kinetic energy, while potential energy is stored in a system of objects. Explore work as a means through which energy is transferred, and apply the principle of energy conservation to analyze changes in a system's energy. Express energy concepts using multiple representations, including bar charts, graphs, and equations. Define power as the rate of change of energy.
