Preliminary Questions 1) Since velocity is a vector, the change in direction suggests there must be an acceleration present 2) Acceleration; F=ma 3) Centripetal Force



Analysis 1) Accelerations from the change in direction 2) Towards the center 3) Also increases 4) No, the velocity is squared, so by a factor of 4 5) The relationship between centripical acceleration and velocity is squared. The a is proportional to v^2.

Application 5) Friction 6) It will skid 7) 4 times as much
