Question

Richard wrote a list of the advantages of using any one of the six simple machines. His list is below. Which statement about simple machines is not correct?

-Some simple machines produce an output force greater than the input force.
-Some simple machines produce an output force in a different direction than the input force.
-Some simple machines have a work output greater than the work input.
-Some simple machines increase the distance through which a force is applied.

Answer 1

Answer: Some simple machines have a work output greater than the work input.

Step-by-step explanation:

Answer 2

Some simple machines have a work output greater than the work input.

Input work is always equal to output work as a machine can multiply force but not the energy. Hence, the above statement given about the simple machine is not correct.
