By the end of this section, you will be able to explain gravitational potential energy in terms of work done against gravity, show that the gravitational potential energy of an object of mass m at height h on Earth is given by PEg = mgh,...

Discusses conservation of energy, and explains what kinetic energy is, some kinds of potential energy, and how work and energy are related using the work-kinetic energy theorem. Provides lots of examples along with calculations.

The energy in the universe never increases or decreases- but it does move around a lot. Energy can be potential or kinetic. George Zaidan and Charles Morton get excited about energy. [3:52]

Read about all the different kinds of potential and kinetic energy. Includes energy formulas and examples of energy applications.
