HOW FORCE IS DETERMINED
Force can be measured by the effect it has on an object with mass. It also can be measured by the amount of deflection or distortion it produces in an elastic object such as a spring. The “mass meter” described earlier for determining mass can be modified to make a “force meter” if one-half of it is taken away and a calibrated scale is placed alongside (Fig. 1). This scale must be calibrated in advance in a laboratory environment.
