               5.3 The Relationship Between Linear And Angular Motion



               5.3.1  Angular Motion
               Consider the below figure.


                                        B

                                r

                           0   Ѳ


                                         A




               When the length of arc AB = the radius of the circle , r, then;

                      Angle A0B      =      1 rad.



                      But,

                      if an arc  AB  =      1 circumference of a circle

                                                   =      2πr, then
                                                              o
                                     angle A0B     =      360 .
               360     1       
                     =
                2           


                      
                      =       



                                                             74
