Discussion: The condition for static equilibrium, F T = 0, was not satisfied for this experiment. The net force at equilibrium should have been 0.00 N; in other words, the ring should have been stationary and not accelerating at all. The uncertainty of F T was 0.0265 N. The net horizontal force was -0.21 N while the vertical force was 0.06 N. The main cause for systematic error was the uncertainty of the equipment, including the weights, balances, and force table. In the event that a weight holder was not doing its job properly, each successive weighing could have contributed to greater error. Any other divergence from accurate results were most likely due to random error.

Unformatted text preview: To improve chances decreasing errors, it would be beneficial to perform the experiment and compare it to others that performed the same experiment. Things learned from the lab included how to calculate sum of vectors using the head-to-tail method, how a force table works, and how to determine uncertainty in mass and angle measure. Engineers would most likely use the information in this lab, as well as physicists and other hard-science occupations. Architects would most certainly find the trigonometry useful in building large structures where measurements are critical....
