Calculating Net Forces - Examples
Interpret each drawing of forces on the box. Calculate and write the resulting net
force on the blank below the box (make sure to include the correct unit of
measure). On the next blank, write the word balanced or unbalanced and circle
the arrow for the direction of the resulting net force. See the examples below.
