Work, Energy, and Power - SFA Physics and Astronomy
... Power measures how fast work is done. It is defined as work divided by time (P = W/t). The units are joules/second, called the watt. The ability to do work is energy. It is measured in the same units (joules) as energy. Lifting an object against gravity requires work (a force equal to the weight of ...

Chapter 8 Potential Energy and Conservative Forces
... Section 8-2 • When a conservative force does work, it shows up as a change in the corresponding potential energy: Wc = –∆U = Ui – Uf. • In the case of gravity the potential energy is U = mgy. Determining the gravitational potential energy of an object requires setting a zero height location. The cho ...
