Loop radius

  1. May 31, 2010 #1
    im doing this eperiment on rollercoasters and i was wondering if loop radius effects the vehicle; like if the loop was to small will it make it through? or if the loop was to big will it make it or just simply fall off? :) THANKYOU

    Hi sillybilly! Welcome to PF! :smile:
    Yes, the minimum safe speed does depend on the loop radius.

    The car will lose contact when the reaction force is zero …

    and you can find when and whether that happens by using good ol' Newton's second law and the formula for centripetal acceleration :wink:
