Well, its not that hard: Some machines help people do work by changing the size of the force needed. Have you ever tried opening a door by turning the shaft instead of the handle? Not as simple. It takes less force to use the handle instead of the shaft. If a machine (doorknob attached to shaft) allows you to exert less force, you must apply that force over a greater distance. the complete and total amount of work done remains the same, whether its by machine or not. Because a machine does not change the amount of work to be done, less force must mean greater distance. So: Machine=less force BUT greater distance!

Wiki User
∙ 9y agoIt can either increase or decrease the output force, as compared to the input force. The output force may also be equal to the input force.

How is a change in an object's direction related to the applied force?
In order to change direction, the applied force (represented as a Vector) must change DIRECTION. A change in magnitude of the Force is not necessary.
What does a pulley do to the direction of a force?
Pulleys change the direction of a force.
What is needed to change the direction of a moving mass?
The answer is force because Force is needed to change the direction of a moving mass.
What changes the direction of a force?
Force changes either the speed or the direction of motion, or both.
Why might someone want to change the direction of a force they apply?
If the work that they want to do is not being accomplished, they may want to change the direction of force. They may also want to change the direction of force due to space constraints.
Name 3 machines that change the direction of a force.?
a windmill
What kind of simple machine is a straw?
A straw is not a simple machine. Simple machines are mechanical devices that change the direction of a force. A straw does not redirect the direction of the force.
What is essence of using simple machine?
Simple machines lets you trade force for distance, or the other way around. Or they change the direction of a force.
What are the types of simple machines and what do they do?
Simple machines are any device used to change the direction and or magnitude of a force. Levers, pulleys, wheels, and the inclined plane are all examples of simple machines.
What are the three things machines chance to make work easier?
Do you mean "change"? If you're talking about "simple machines", the usual answers are direction (eg., with a pully), speed, and force.
What is the term for a tool that make easier by change the size or direction of a force?
machineAre you referring to simple machines?wikipedia.org/wiki/Simple_machinemachine
How is a change in an object's direction related to the applied force?

Still other machines allow you to change the direction of the input force resulting in a mechanical advantage equal to one?
Yes, sometimes a pulley is used just to change the direction of the force, rather than to create a mechanical advantage. This can also be done with gears.
What does a pulley do to the direction of a force?
Pulleys change the direction of a force.
How do simple machines change the force?
by levers
What is needed to change the direction of a moving mass?
The answer is force because Force is needed to change the direction of a moving mass.
What changes the direction of a force?
Force changes either the speed or the direction of motion, or both.
