The equation 'work = -δu' expresses the relationship between work done on a system and the change in potential energy of that system. Here, work represents the energy transferred when a force is applied, while 'δu' denotes the change in potential energy. This connection is fundamental in understanding how energy is conserved and transformed within physical systems, highlighting the interplay between mechanical work and potential energy changes.
congrats on reading the definition of work = -δu. now let's actually learn it.
