Velocity Ratio:
This is the ratio of the distance moved by the effort to the distance moved by the load in the same interval of time. Thus,
Velocity Ratio $(= \frac{D}{d})$
Mechanical advantage:
This is the ratio of load lifted to effort applied. Thus, if W is the load and P is the corresponding effort, then
Mechanical Advantage $(= \frac{W}{P})$
There is no change in velocity ratio or mechanical advantage of a simple machines with the change in friction.Other Questions
