There was such a strong upward lift on the bottom of all cars that race officials had to adopt SAFETY requirements MANY years ago. Wings were required to provide a downward force to keep the car from RISING off the ground. The same thing is true for powerboats traveling at speeds of 100 mph. Now I want to know if a 5 ounce baseball with SEAMS passing through the heavy warm AIR I breath at sea-level in June at speeds of 100 mph also experiences a small RISE due to a well-known force called LIFT.

I saw a car get air under it and leave the track in the 1st turn at the ROCK many years ago. The turns are banked pretty good so it took another car bump to get wind under the car to make it leave the track. Wings provide lift for an airplane to fly. Spoilers help keep race cars on the track, although they will get up if air gets under them. NASCAR is a different subject entirely from a fastball that is thrown at a downward angle toward the plate, and once released can not accelerate, it can only slow down, and drop.

Yes, you are correct. NASCAR cars only flip when they are spun around backwards, causing air to be trapped underneath the rear of the car. This creates so much push that the air packs in under the rear of the car, and flips it. It has nothing to do with a fastball, total moot point.
