• Select the object
• Establish n, t, b coordinate system
• Set an always acts in the positive n direction
• Assume at acts in the positive t
• Set W mg always acts in a vertical
directiondownward
• Set normal force FN along normal line
• Set frictional force Ff opposite to t direction

n
• tan-1(dy/dx)
• Between vertical and normal
• positive negative
