When lifting an object vertically, would either Fn or Fg be longer on a free body diagram? Explain.

It depends. Net force = mass * acceleration
force down = m g = Fg
force up = Fn (I suppose although you did not say)
Fn - Fg = m a
if the acceleration, a is up, Fn is bigger
if the acceleration, a is down, Fg is bigger
force down = m g = Fg
force up = Fn (I suppose although you did not say)
Fn - Fg = m a
if the acceleration, a is up, Fn is bigger
if the acceleration, a is down, Fg is bigger
