| But how can we find out whether the U.S. economy has too much, too little, or the right amount of frictional unemployment? |
| The direction of the frictional force always opposes the direction of motion. |
| Air resistance is a type of frictional force and it is worth considering some general points about friction first. |
| Students might enjoy researching some of the ways in which frictional forces are minimized in such sports. |
| In another embodiment, sliders are carried in the support surface of the platen to minimize frictional contact with the moving belt. |
| This is a result of a decrease in frictional drag due to removal of body hair. |
