   What you feel is centripetal force (not acceleration), because force is   
   felt, acceleration is not.   
      
   And when (jumping on the merry-go-round) you feel the centripetal   
   force, the pole you cling to feels your centrifugal force!   
      
   You could never feel the centripetal force of the pole you cling to if,   
   at the same time, the pole did not feel your centrifugal force.   
      
   And when you jump off the merry-go-round, the two forces disappear   
   together exactly as they were born together!   
      
   The centripetal force of the pole and your centrifugal force travel   
   *together*: both are there or both are not.
