Question

Which of the following statements describes a way that simple machines make work easier?

1.  change the direction of the input force
2.  reduce the amount of energy needed to perform a task
3.  reduce the size of the input force needed to perform a task

Answer 1

I don't see the 'direction of input force' or reduction of size of input force' needed to perform a task actually 'making the work process easier'. Simple machines did reduce the amount of energy needed to perform tasks, making it easier for people to complete projects quickly and without so much physical exertion. In this way, workers were able to complete work without as much effort. I hope this helps.
