Homework Help: Draw a free body diagram of each object in centripetal acceleration

  1. Apr 7, 2013 #1
    1. The problem statement, all variables and given/known data
    Draw a free body diagram of each object in Italics, that is in centripetal acceleration, and name the force causing this centripetal acceleration.
    a. Moon in circular orbit around Earth.
    b. Electron in circular orbit around nucleus of atom .
    c. Snowboarder slides over top of a bump that is in the shape of a circular arc.

    2. Relevant equations


    3. The attempt at a solution

    a. See Pic 1. The force is force of gravity exerted by the Earth?
    b. Same as Pic 1. The force is Fg exerted by the atom?
    c. There is a Fn and Fg on the snowboarder, I think. The Fg must be greater such that it can 'supply' the required Fc (centripetal force).

    Thanks so much in advance. :) :)

    The notation 'Fg' suggests gravity. It's not that.
