Efficiency of a ramp

  1. Oct 19, 2003 #1
    i kno this is basic physics compared the other stuff u guys are talkin about but im still a kid and i need help :wink:

    i need to kno the relationship between the efficiency of a ramp and its the mass of the cart rolling up it, the efficiency of a ramp and its slope and the efficiency of a ramp and friction

    i also need to kno one advantage and one disadvantage of using a ramp rather than lifting an object vertically

    any replies are greatly appreciated thanks !!

    Then read your text book and find them out for yourself. That will help you learn a lot more than someone else giving you the answers.
