how do you determine the relationship between the angle of a ramp and speed of an object sliding down the ramp?
The vertical distance that it falls determines the speed, in the frictional case. The component of the weight in the direction along the slope determines the acceleration.
The acceleration ig g sin theta along the plane.
Friction makes things more complicated. You need a certain minimum tilt angle to overcome friction and move at all.
