Conservative & Nonconservative Forces, Kinetic & Potential Energy, Mechanical Energy Conservation

Подробнее о видео

This physics video tutorial provides a basic introduction into conservative and nonconservative forces. Examples of conservative forces include the electric force, the elastic force, and the gravitational force. Examples of nonconservative forces include friction, the applied force, any push or pull action including the tension force. This video connects the work done by conservative and nonconservative forces with the conservation of mechanical energy and shows how it's related to the change in the kinetic energy and potential energy of an object.
