The gravitational constant G, no, the mutual gravitational force between the earth and the ball approximated as g, yes.

Edit: Since this is a little pedantic, G is used to calculate g.

But how would that make the bowling ball fall faster? F = G × m₁ × m₂ / r² and F = m₁ × a ⇒ a = F / m = G × m₂ / r², where m₁ is the mass of the ball and m₂ the mass of the planet. So the gravitational acceleration of a bowling ball is independent of its mass (assuming the planet has way more mass than a bowling ball).
