Does a machine do less work when friction in a machine increases?

Yes. Since more work goes to counter the friction force, less work goes to do the actual function of the machine.

How does the output work done by machine change when friction is reduced?
Increases
Does the simple machine reduce overall work needed?
No. Work out is always less than work in due to friction and other losses..
Explain why the amount of work that a machine does is less than the amount put into the machine?
Output work is always less than input work.
How does the output work compared to the input work for a machine that has an efficiecny less then 100?
the efficiency of any machine is NOT 100% because some of the input work is used to compensate for the work done by friction.
Is the work output of a machine is always less then the work input where does the missing work go?
The energy, lost to friction, is converted to heat and sound.
If the work output of a machine is always less then the work input where does the missing work go?
The energy, lost to friction, is converted to heat and sound.
Can you work on friction less floor?
No, We cannot do work on friction less surface
How is the work output of a machine related to it's work input?
In an ideal universe, where there are no friction or heat transfer losses, work out = work in. In our universe, however, work output is always less than input. How much less depends on the efficiency of the machine's design.
How are friction and force related?
friction increases the amount of force necessary to do work
Why is the output work in a machine always less than the input work?
Every real machine is subject to forces that reduce output. These include actual forces such as friction, or human controlled forces such as imperfect machining. This reduces the output to less than the ideal.
What causes the output work of a machine to e less than the input work?
Some of the input force is lost due to friction. If you are using a pulley system then there is friction between the rope and the pulley and there is also friction within the ball bearings of the pulley itself. If you are using an inclined plane there is friction between the plane and the object traveling upon it. In a friction-less world the input is equal to the output.
When using a real machine to do work input work will always be?
Work output is always less than work input because some work is lost to friction and heat which is created in the process of physics.
