Spring-Mass Problems An object has weight w (in pounds
... is defined as some force (in pounds) acting against the bobbing mass when the mass is at some speed, given by . This resistive force is usually proportional to the speed, and acts against the motion of the object. Thus, we can write , where is the constant of proportionality. The sum of all of the f ...
