F (centripetal)= mv^2/r ... its v squared thats the tough part. You have actually slow down to not lose as much energy to hold you in that turn. Any time anything turns it changes direction. Any time a body changes direction it accelerates (changes velocity). Any time a body accelerates a force is required. And I thank you. |

You quote pgardn, and then do not address at all the valid point he makes. It takes energy to make tight turns. This should be intuitively obvious to anyone who has applied the brakes to a car making a tight turn. I'm not sure how to quantify the effect for horses, but I suspect it must be a real effect for some horses. It's going to be less important at a big oval like Belmont than at a smaller track. I can remember horses almost skidding around the turns at Sportsmans Park. --Dunbar

![]() I give Borel credit, the guy has guts. Way too many jocks go wide every chance they get. Calvin understand geometry .
