Why use the change up grip instead of throwing a softer 4 seam fast ball?What are the physics? Also should i give any movement to the change up if so how?

Because changing your pitching motion and/or arm speed for a change-up will tip off the batter that a change-up is coming. Always pitch with the same pitching motion and arm speed. Change only the grip.
