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.

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.

its the force and work assingment if u have all answers i really want to check my answer just in case
4. They reduce the amount of force needed to move an object to do the same amount of work.
Simple machines are like the lazy friends of the work world. They're always finding sneaky ways to help you do less. It's like they have a magical power - the ability to make work easier. By using simple machines, you can get more bang for your buck, or should I say more work for your force? These machines do the heavy lifting for you, so you can kick back and relax. Who needs a gym when you have simple machines to do your bicep curls? So next time you need to move something heavy, just remember to call on your trusty simple machines, the ultimate work hack.
The correct answer is option 1: They decrease the distance needed between a person and an object, allowing the person to apply more force and do more work.
Simple machines make work easier by reducing the amount of force needed to move an object or do a certain amount of work. They achieve this by changing either the magnitude or direction of the force applied. In the case of reducing the amount of force needed, simple machines accomplish this by decreasing the distance required between the person using the machine and the object being moved.
To understand why this decreases the amount of force needed, it helps to look at the concept of work. Work is defined as the product of force and distance, where force is the amount of effort exerted and distance is the displacement of the object in the direction of the force. By reducing the distance between the person and the object, the force required to move the object over that shortened distance is also reduced. This allows the person to apply more force and do more work, even though the overall displacement of the object may remain the same.
In summary, simple machines make work easier and reduce the amount of force needed by decreasing the distance required between a person and an object, allowing for the application of more force and the ability to do more work.
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
