@timo , thanks i get it now .

Can you guys explain it in a more simplified manner , I don't think you are getting my point , @timo an fair experiment is conducted with gradient as independent variable. And of course , the force supplied to start the ball rolling is constant for both scenarios. I was wondering if its correct to say that the steeper the gradient , the greater the effects of "free fall". Another possibility is that the reaction force during point of contact of slope and ball is smaller for the steeper slope , hence it experiences a greater force due to gravity.

We know that when a circular object is placed on a ramp , it will " roll down the ramp ". How gentle or how steep the ramp is will affect the velocity of the object. My question is that whats the exact explanation for how the gradient affects the speed. My guess is it has to do with moments , am I right?
