Circular Orbits

  1. Nov 3, 2007 #1
    Hi i am doing a lab on circular orbits similar to this one: http://www.batesville.k12.in.us/physics/phynet/mechanics/Circular Motion/labs/cf_and_speed.htm

    I was wondering if someone can tell me what the main sources of error are, as well as the most significant source of error.

    Also, i am not clear on what the slope of a T(period of rev) vs L(length of string) graph means. I made an experimental T vs L graph and a theoretical T vs L graph, however, i had to square the T so i get a straight line so its really a T^2 vs L graph. Basically, i want to know the relationship between T and L.

    Finally, i have a post lab question that asks: Discuss how the results of your experiment would be affected if the ratio of the masses used was 1:2 instead of 1:3. How would this affect A)the angle between the string and the vertical glass tube B)the relationship between the period of revolution and the length of the string?


    Thanks in advance
