Answer:

Velocity ratio

Explanation:

in real situation,due to weight of parts and friction mechanical advantage decreases while velocity ratio remains constant as it's the ratio of distance moved by effort and distance moved by load which is obviously constant.

efficiency is just their ratio so it will change since ma will change
