               Uniform Circular Motion

                     PSPM 2017/2018  SF016/2  No. 4(a)(ii)

               1.    Define centripetal acceleration.                                               [1 m]



                     UPS 2001/2002  SF015  No. 5(a)

               2.    Does a body moving in a uniform circular motion have acceleration? Explain briefly.
                                                                                                    [2 m]


                     PSPM 2013/2014  SF016/2  No. 4(a)(ii)

               3.    Why is the direction of centripetal acceleration always perpendicular to the velocity?
                                                                                                    [2 m]

                                                                P   Q





                                                          FIGURE 6.1

                     Sketch the change in the velocity of an object due to position P and Q which will show
                     that the object is in a uniform circular motion as shown in FIGURE 6.1.        [2 m]


                     PSPM 2008/2009  SF017/2  No. 11(b)

               5.    Calculate the centripetal acceleration of an object at the equator due to rotation of earth.
                                                  6
                     The radius of earth is 6.4 × 10  m.                                            [4 m]


               Centripetal Force

                     PSPM 2013/2014  SF016/2  No. 4(a)(i)

               6.    Define centripetal force.                                                      [1 m]
