The ratio of Mechanical Advantage and Velocity Ratio is Efficiency. That is to say the ratio of M.A. and V.R. is constant.
The relationship between mechanical advantage, velocity ratio & efficiency is:-
efficiency=Mechanical Advantage/Velocity Ratio
The velocity ratio is always greater than mechanical advantage in a simple machine. The output work is always less than the input work.
They both characterize the frictionless mechanical advantage of a machine
The mechanical advantage of a First Class lever is Distance of the effort from the fulcrum/Distance of the load from the fulcrum
the difference between the real mechanical advantage and the speed ratio is -the real mechanical advantage gets affected by friction so the real mechanical advantage gets smaller than the mechanical advantage you calculate. so the real mechanical advantage gets smaller than the speed ratio (because of the friction) and that's why the efficiency never gets 100% efficient (efficiency ; mechanical advantage/ speed ratio x 100(%))
velocity = displacement / time taken
Acceleration is the rate of change of the magnitude of velocity and the direction in which the velocity changes.
The mechanical advantage of a lever is the ratio of the length of the lever on the applied force side of the fulcrum to the length of the lever on the resistance force side of the fulcrum. There are three types of levers - class 1, class 2, and class 3.

The mechanical advantage of a First Class lever is Distance of the effort from the fulcrum/Distance of the load from the fulcrum
the relationship between them is that the load carries it self and the lever holds its self in place

Momentum=mass*velocity
The lighter the weight, the greater the initial velocity of shortening; inverse relationship.
