Question

How do simple machines make work easier?(1 point)

1.They decrease the distance needed between a person and an object, allowing the person to apply more force and do more work.
They decrease the distance needed between a person and an object, allowing the person to apply more force and do more work.

2.They magnify the force being applied, thereby decreasing the work they can do with no extra energy exerted by the person using the machine.

3.They increase the distance over which a force is needed, doing more work with less force.

4.They reduce the amount of force needed to move an object to do the same amount of work.

Answer 1

as the force you exert goes down the distance you move your hand goes up :)
meanwhile the force on the object goes up and the distance it moves goes down.
The work out = the work in if perfectly efficient
so

Answer 2

its the force and work assingment if u have all answers i really want to check my answer just in case

Answer 3

Hey wha, I am just a dumb old retired college professor and do not have the slightest idea what your text or assignment is. Moreover I do not have all the answers to much of anything.

Answer 4

B.) They increase the distance over which a force is needed, doing more work with less force.
