What simple machine reduces friction?
If I'm not mistaken, there is no machine that can reduce friction. The machine is intended to change the distance the input force is applied over or to multiply the output force. The moving parts of the machine will always increase friction. In order to reduce the extra friction (but not completely remove it), one would use a lubricant or reduce the roughness between two surfaces. Hope it helps.
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.
What do wheels and gears of a machine are greased in order to decrease I know the choices are potential energy efficiency output and friction?
Friction is decreased.
Why is it impossible for the output work of a machine to be greater than the machine's input work?
There are always energy losses within the machine due to inertia, friction, etc.
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.
What is the difference between a ideal machine and real machine?
In ideal machine input is equal to output . The efficiency of ideal machine is 100% . In real machine input is not equal to output .The efficiency of ideal machine in not 100% . In ideal machine there is no lose of energy . In real machine there is lose of energy . In real machine there is no friction . While in real machine there is friction .
How does friction affect output force?
Simply put, friction reduces output force. The more friction there is, the less effectively power will be delivered, and this results in reduced output force.
How does the output work done by machine change when friction is reduced?
Increases
How does friction affect the equality between work input and work output in real situations?
Work Input = Work Output + Work done in overcoming friction.Therefore Work Input > Work Output.
How lubericating a machine affects the output force exerted by the machine?
It maximizes it, by reducing the internal losses to friction.

Why is the work output of a machine never to the work input?
Some work input is used to overcome friction.
