# Greater influence on movement: Mass OR Gradient?

1. Which, if any, has the greater influence on rate of movement down a slope with a constant distance of 80cm: the gradient of the slope or the mass of the object moving down the slope?

2. acceleration = net force / mass

3. If the slope is 90 degrees, the rate of movement of falling objects with different masses would be the same because the acceleration of an object is inversely proportional to its mass.

Am I on the right track here? Any assistance will be appreciated. Thanks in advance

and how big is that net force?

Thanks for your reply willem2. The object moving down the slope (a small glass marble) weighs 3 grammes. This is all the info I have, hope this answers your question.

I was wondering generally speaking, what would have a greater influence on movement of a object, its mass or the slope?
