Physics 211 Fall 2001 Concepts and Equations t v a = Defines acceleration in terms of how the velocity changes. v v v i f + = How two instantaneous velocities are related to the change in velocity. t x v ave = Or the “mid-time” velocity. Defines displacement and average velocity. a x t = 2 Only if the initial velocity is zero. May not use this to find x or acceleration. hyp opp = θ sin hyp adj = θ cos adj opp = θ tan g m W A A E = , B A k B A N f , , μ = Kinetic friction B A s B A N f , max , μ = Max static friction a m F net = Second Law

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
