Radiometry and Photometry - University of Washington
depts.washington.eduwatt, E( ) is the spectral power in watts per nanometer, and V( ) is the photopic spectral luminous efficiency function. Note that the integration is only carried out over the wavelengths for which V( ) is non-zero (i.e. = 380 -830nm). Since V( ) is given by a table of empirical values, it is best to do the integration numerically. W. Wang

Chapter 6 Work, Kinetic Energy and Potential Energy
www2.tntech.eduThe unit of power is the watt, defined by: 1watt = 1W = 1 J s = 1 kg·m2 s3 (6.16) The watt is related to a quaint old unit of power called the horsepower: 1horsepower = 1hp = 550 ft·lb s = 746W One can show that if a force F acts on a particle moving with velocity v then the instantaneous rate at which work is being done on the particle is
