By exchanging for for distance. You need to apply less force, but you need to apply it over a larger distance. Since work (or energy transfer) is force x distance, the total work is the same.

Which Objects reduce turbulent flow over water and air?
To reduce turbulent the key is to have streamlined shape of an object.
If the machine cannot multiply the amount of work what is the advantage of using a machine?
A machine decreases the amount of force needed to work, as it distributes the force throughout a larger distance.
Two ways to reduce friction are to use what?
Reduce contacting surface area between the two objects, and to use lubrication.
What reduces the force of gravity between two objects?
Two things reduce the force of gravity between two objects: an increase in the distance between the two objects or decrease in mass of the two objects
What does simple machines change?
Simple machines such as pulleys, wedges, and levers reduce the amount of energy required to lift or move (heavy) objects.
What statements describes a way that simple machines make work easier?
Simple machines help people lift and pull heavy objects. Simple machines like pulleys have been around for decades helping people work more efficiently.
What is the purpose of a inclined plane with a pulley?

What are simple machiens?
simple machiens are the thing which reduce human effort
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.
Why do you streamline objects?
To reduce friction.
How do simple machines make work about the same?
They do not. Simple machines reduce the effort used to do a task.
What is the rubber bar of the vibrating?
Reduce the vibration and protect the machines.
Why is an oar a class 2 lever?
An oar is a class 3 lever. This is because the oar, like all class 3 levers, is not used to reduce the force needed to move the load, but is used to increase the amount of travel of the load.
What is the definition of reduce?
Reduce means lessening the amount of items or resources that are needed and using only the amount that is needed
What was the goal of victory gardens?
