Description
6.4 Integral Applications Force and Work Applications Question #1 (Easy): Work Done Based on Constant Force Strategy The key is to differentiate the components that represent the force needed to calculate the work done. The equations are: 1) 2) For work done, first the force needs to be calculated because it is used as input for work calculation. In the International metric system, force is in Newton ( ), distance is in meters ( ); therefore work is in (called Joule ). In the US metric system, force is in pounds ( , fundamental unit of force), distance is in feet ( ); therefore work is in foot-pound ( ). Keeping track of the units is very important.
