In class we discussed how a scientist would classify work being done. Know that you need 2 things: force and distance. If one of these elements is missing then there is no work being down. You should have learned that laying on the couch does not count as you doing work!
Complete the practice problems for homework (they are on the back of the circuit paper). Lost the paper? See link under Class Info. Remember that the equation is Work = Force * Distance
