                          2.  A fan uses rotational motion to spin.

                          3.  Oscillating motion is used to make swings move back and forth.

                          4.  Gears help things move slower or faster.

                          5.  All objects use circular motion to move.

                      C.  Fill in the blanks.

                          1.  A wheel turns using                   motion.

                          2.  A swing uses                 motion to move back and forth.

                          3.  Gears work together to create                     motion.
