Heavier object does in fact fall faster than lighter object

well, not fall but roll down an incline.
maybe I am the idiot here, but I thought we were all taught that the mass is taken out of the equation when calculating acceleration in falling and rolling objects.[/u]
Clearly this is no the case. take two like size objects with 2 different masses and the heavier one will always roll faster, and accelerate faster too.
this is one of the premisis that our machine uses.

in the initial event they will but both will attain terminal velocity of the same speed, no?

[cameron sydenham]

i think that yes, they will reach the same speed, but i did this expirement, and wow, it is a huge difference in speed, especially when you do it in a circular motion and apply the dynamics of angular velocity to it, then the heavy one really surpasses the lighter one.

That's interesting.  You are repeating the famous experiment by Galileo.  There is a myth that Galileo dropped objects of differing weights from the Tower of Pisa.   Historians doubt this actually happened, but what we know for sure did happen is that Galileo conducted many experiments with balls and ramps.  The consistent result was that balls of differing weight would always arrive at the end of the ramp at the same time.

Your results are at odds with this.  Could you describe your experiment?  What kinds of objects did you roll.  What was the ramp like?

that is interesting, i read something about that yesterday. here is what i am doing. take a pvc pipe as the medium, cut into 3 or 4 different exact lengths. leave one hollow, and fill the other 3 with different material, i am using jb weld, liquid nail and a metal rod in the last. each one rolls down any incline at different speeds. I also did this with a brass ball the same identical size of a lighter ball, .... i have done with alot of different things, same result, the heavier one always wins.

the way i understood gallileo was he was watching how far the rolled, i was unable to find any where that he "raced" them. i could be wrong but in my expirements, on a slight incline, the heavier one always wins.?!!

i cut and pasted this from  http://www.batesville.k12.in.us/physics/PhyNet/Mechanics/RotMechanics/fall_slide_roll.htm

If you "race" these objects down the incline, they would definitely not tie! This is because Newton's Second Law for Rotation says that the rotational acceleration of an object equals the net torque on the object divided by its rotational inertia. (Net torque replaces net force, and rotational inertia replaces mass in "regular" Newton's Second Law.) The net torque on every object would be the same - due to the weight of the object acting through its center of gravity, but the rotational inertias are different. This means that the solid sphere would beat the solid cylinder (since it has a smaller rotational inertia), the solid cylinder would beat the "sloshy" cylinder, etc. The hoop would come in last in every race, since it has the greatest moment of inertia (resistance to rotational acceleration).
