   A tube is diametrically fixed on the carousel.   
      
   In the tube there is a little ball free to move, which is "fired" out   
   like a bullet.   
      
   In the rotating reference of the carousel (and until it is inside the   
   tube) the "projectile" moves outwards with increasing speed, ie with   
   acceleration?   
      
   If the answer is yes, the force that accelerates the ball in the tube   
   is the "centrifugal" force?   
      
   And if even this answer is yes, is this force real or apparent?
