what makes water in the mountain go slow or fast
The steepness of the slope is what determines its velocity, mainly. There are other factors, such as how deep it is, and how straight is the path it follows. If you ever get the chance to follow the Arkansas River up to the Mountains in Colorado, it is a very nice sight to observer all this.\
umm... this is really not a question, but the easiest way to do this method is the Line graph. To find an object's velocity, you must determine it's mass, and it's speed. Multiply them to find the objects velocity.
That is all
iT DEPENDS IF THE MOUNTAIN IS ROUGH OR SMOOTH. WHEN IT IS SMOOTH THE WATER IS EASIER TO PASS THROUGH.
