    (i) Mechanical advantage: Mechanical advantage is the ratio of the force applied to a simple machine to the force output by the machine. It is a measure of how much the machine amplifies the force applied to it.

    (ii) Velocity ratio: Velocity ratio is the ratio of the distance traveled by the input force to the distance traveled by the output force in a simple machine. It is a measure of how much the machine increases or decreases the speed of the input force.

    (iii) Efficiency: Efficiency is the ratio of the work output by a simple machine to the work input to the machine. It is a measure of how much of the input work is converted into useful output work, with the remainder being lost to friction and other sources of energy loss.
