What is the resistance force or the work a machine dose to move an object over some distance?
The resistance force is the opposing force a machine must overcome to move an object over a distance. The work done by the machine is the product of the force applied and the distance over which the object is moved.
Why the output force exerted by a rake must be less than the input force?
because you need the force to move it over some distance
What is force distance trade off in a simple machine?
That means that if you use a simple machine to apply less force, you need to compensate by applying the force over a larger distance - for example, to lift up a weight or do some other work.
What is an example of a pneumatic fluid?
The main function is the transfer of force from one point to another. Some pneumatic machines also obtain mechanical advantage by converting a small force applied over a large distance to a large force applied over a small distance.
What is work over force times distance?
The force is an important part of life for both Jedi and Sith alike. Distance is very important, as you may have noticed in some of the films, some weaker individuals can only project force over short spaces, but more powerful people can even project force across large rooms, ex: Darth Vader
If a machine allows you to use less force to do some amount of work then you must apply the input force over a greater?
Yes, that's correct. In order to reduce the force needed to do work with a machine, you typically need to increase the distance over which the force is applied. This is described by the principle of mechanical advantage.

because you need the force to move it over some distance
Is there any work done when a person takes a bucket to some distance?
The question is incomplete. If the bucket is taken in a horizontal plane then no work is done If the bucket is taken in an inclined plane then work has to be done against force of gravity
What is the use of force to move an object some distance?
The use of force to move an object some distance is called work. Work is calculated by multiplying the force applied to an object by the distance the object moves in the direction of the force. Work is measured in joules.
Who is greater the applied force or the force exerted by the machine?
That depends on whether the machine is designed to multiply force or distance. A machine designed to multiply distance will exert less force than was applied, and a machine designed to multiply force will exert the greater force over a shorter distance than force was applied to it. As for work, output work is always less than input work because some energy is lost in overcoming friction.
If two objects have a force of 800 pounds at some distance what will the force be if the distance is tripled?
Presuming we're talking about gravity here - since the force varies with the inverse square of distance, at triple the distance the force would be one ninth as strong or (800 / 9) pounds.
What will happen to the force of gravity if the mass of one of the objects is tripled?
You didn't specify what force. some forces have an inverse-square relationship. That is to say, the force of gravity, or electrostatic attraction or repulsion, is inversely proportional to the square of the distance - if the distance is tripled, the force is reduced by a factor of 9.You didn't specify what force. some forces have an inverse-square relationship.
