Centripetal Force
... A bicyclist negotiating a turn on level ground must lean at the correct anglethe ability to do this becomes instinctive. The force of the ground on the wheel needs to be on a line through the center of gravity. The net external force on the system is the centripetal force. The vertical component of ...
