ENERGY

ENERGY. ENERGY is present in the Universe in a variety of forms, including mechanical, chemical, electromagnetic, and nuclear energy. Mechanical energy , is a sum of Kinetic energy (the energy associated with motion), and potential energy (the energy associated with position).

Chapter 6: Work and Energy

Chapter 6: Work and Energy. Christopher Chui. Work Done by a Constant Force. Work is defined to be the product of the magnitude of the displacement times the component of the force parallel to the displacement, or W = Fd cos q Unit for work is joule, or 1 J = 1 N-m
