I just answered the same question and you can see it in the link link.

This is the same answer.

The work OUTPUT of a simple machine can never exceed the work INPUT because FRICTION uses some of the work.

Explanation:

This concept is related to ideal machines and efficiency.

Only ideal machines can convert all the work input into useful work (work ouput).

The efficiency is a concept that tells you the proportion of input work that is transformed into output work.

         Efficiency = (output work / input work) × 100

Ideal machines, those where friction does not exist, have a 100% efficiency, and so ideal machines convert all the input work into useful output work.

Real machines have a efficiency less than 100%. Friction lowers the efficiency and the work output is less than the work input, because friction uses work which is converted, mostly, into heat energy or sound energy.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
