Does value of gravity affect the angle at which an object slips for a fixed μ? why or why not?

 If not, what physical quantities are affected by an increase in gravitational field strength?

    No it does not, because gravity affects both the motive force (m*g*sinΘ) and the resistive force (µ*m*g*cosΘ) in the same proportions. Instead,

    Θ = arctan(µ)

    only.

    Changing "g" will change an object's weight as well as the period of a pendulum. It would affect pressure everywhere, and that would affect the density of gases (as well as liquids to a much lesser extent) -- the density of air at sea level would be higher (with increasing "g") and the density at elevation less. Escape velocity would increase. The list goes on and on.
