Stunning physics

  1. Mar 2, 2010 #1
    So. I stumbled upon this brilliant little deuction; it is simply marvelous.

    This can be used when anyone needs to find the acceleration due to grav. When opposed by normal force equal to the objects weight in the y direction.

    net force = normal force(call it n) - mg*sinA = 0

    n = mg*sinA
    n/m = g*sinA

    this is the tricky part, because n is one farther in the alphabet than m, n/m simplifies to a

    so a = g*sinA
