That heavy things fall to earth the same speed as lighter things.

I don't think that's right, Larni. Falling to earth is affected by air resistance, so it would slow the lighter object down. I think you mean in a vacuum they "fall" at the same rate?

Air resistance is dependant on the shape of the object not the mass.

True that; I should have been specific.

acceleration due to gravity is not related to the masses of the objects.

Isn't it directly proportional to the mass of the object under the effects of only gravity?

And when you include inertia it would be, because the gravitational and inertial masses are equal for all objects thus irrelevant.
Is that right?
