By simple machines, I assume you mean machines powered by muscle but using leverage such as levers, screws, block and tackle devices. Is that what you mean? If so, these devices increase something called "mechanical advantage".
Start with levers. The usefulness of a lever depends on where the fulcrum is placed. If the fulcrum is in the centre of a lever such as with a see-saw, there is no mechanical advantage at either end. That's why kids of similar weights can suspend the kid on the other end of the see-saw up in the air just to be rascals. Now if the fulcrum is closer to one end than to the other, the person farther from the fulcrum can exert more force than the person closer to the fulcrum. Think of a crow bar. One inserts an inch or two of the bar at the point where one wants to apply force. Pushing on the other end of the bar (perhaps two, three, four feet away) exerts a lot of force at the other end. The same effect allows you to lift a car with a jack. You push down a foot on the jack handle and the jack platform rises perhaps half an inch.

3 ways simple machines make work easier?
Machines make work easier by: -Changing the amount of force you exert -Changing the distance in which you exert your force -Changing the direction in which you exert your force

When two or more simple machines work together they are called?
When simple machines work together, that forms a compound machine.

ANSWER: work input equals work output
Im most simple machines the work output of a machine will overcome the what?
Work input.
Describe how simple machines make work easier?
Simply put, a simple machine makes the work much easier. Simple machines reduce the amount of force needed to do the work. A pulley, for instance, is a great example of a simple machine.
How do simple machines reduce the amount of work required to perform tasks?
Simple machines reduce the amount of work required to perform tasks by changing the direction or magnitude of the force needed to move an object. They make work easier by increasing efficiency and allowing us to accomplish tasks with less effort.
How do simple machines make work about the same?
They do not. Simple machines reduce the effort used to do a task.
Do we do less work if we use simple machines?
Simple machines make work easier by reducing the amount of force or effort required to perform a task, but they do not reduce the total amount of work done. The work input and output remain the same; however, simple machines allow us to distribute the work over a longer distance or apply the force in a more convenient direction.
Do simple machines change the amount of work done?
No you still do the same amount of work
Does using machines reduce the total amount of work required to move an object or make it easier?
Yes. Use simple and compound machines always get things done faster and better.
Do simple machines change the amount of work being done?
No you still do the same amount of work
What does it mean when someone says Simple machines make work easier?
Simple machines are mechanisms that require only one input force to accomplish specific tasks, such as lifting or moving objects. By using simple machines, individuals can apply less force over a greater distance to achieve the same amount of work. In essence, these devices reduce the amount of effort needed to perform tasks, making work more manageable and efficient.
How can simple machines work easier?
They increase the amount of work over a longer period of time.
Why do simple machines do the same amount of work to complete a task as not using the simple machine?
Because the action requires the same amount of force.
What are some common questions about simple machines?
Some common questions about simple machines include: How do simple machines make work easier? What are the different types of simple machines? How do simple machines affect force and distance in work? How can simple machines be combined to create complex machines?
When doing work you can decrease force by?
When doing work, you can decrease force by using simple machines like pulleys, levers, or ramps to distribute the force needed to perform the work. These machines help reduce the amount of force required to move an object by increasing the distance over which the force is applied. Additionally, using lubricants to reduce friction between surfaces can also decrease the force needed to do work.
