Recognition and usage of centripetal and centrifugal forces can and should be developed. If you spin a conker around your head on a piece of string the conker stays in its orbit because the centripetal and centrifugal forces equalise each other. If the string wraps around your finger as the conker spins the conker gets closer to the centre. If you let go of the string, the conker flies off at a tangent. Likewise, tori can draw uke in in a spiral, like the conker, and then let uke fly off - with a little extra power added for good measure.
Centripetal force can be used when you enter tenkan and draw uke in. If you are crafty, you may also be able to use centripetal force in your irimi techniques. Use uke's initial movement, and then add some while drawing in. Obviously, the more you can add the more powerful your technique becomes. Too much too soon and uke might even fall down before the technique is finished.
Centrifugal force is that which is used to spit uke off. Likewise, the more you can add, the more powerful your technique becomes.
You can, and should, develop such power. But use it carefully!
