I hope everyone went out and worked at the family fair or spent lots of money. did you notice all the physics there? on those kiddy rides, kids get in the seat and are spun around the center, with a force equal to the mass of the kid(s) and seat times the velocity squared they're going divided by the radius of the ride. The force is directed radially inward and the velocity is always tangent. Wow, it just so happens that we were reviewing that this week. Don't you love physics?
