one way to reduce friction between two surfaces is to add oil. oil fills in the gaps between surfaces , and keeps many of the high spots from making contact. because there are fewer contact points between the surfaces, the force of friction is reduced. more of the input work then is converted to output work by the machine.

What reduces efficiency by converting some work into heat?
friction
Reducing friction in a machine increases or decreases?
Deceasing friction increases efficiency and reduces heat loss.
Why do wheel reduce the force of friction?
Wheels reduces the friction because to improve the speed of the machines. friction can be reduced with the help of the lubricants.
What is one harmfull way friction affects a car?
Creates heat in the engine (friction of moving parts creates heat) Reduces efficiency (friction in the drivetrain, as well as air resistance, slows the car down) Causes the tires to wear out (friction between the road and the rubber causes the rubber to wear)
Friction reduces efficiency because energy is lost as?
heat energy + sound energy
What reduces the efficiency of machines?
It would be friction.<3 hope this helped
Why doesn't any system have 100 percent efficiency?
frictionIn real machines, as opposed to ideal machines, there is always friction that reduces the efficiency of the machine. Lubricants like oil can be used to reduce friction and improve efficiency.
Which force reduces the efficiency of machine?
Friction.
Why does applying lubricant to a machines surface improve its efficiency?
It reduces friction between surfaces - and stops components from heating up too quickly.
What reduces efficiency by converting some work into heat?
friction
Friction reduces efficiency because energy is lost?
Yes, exactly.
Reducing friction in a machine increases or decreases?
Deceasing friction increases efficiency and reduces heat loss.
Friction reduces efficiency because energy is lost as what?
Mainly as heat (thermal).
Why do wheel reduce the force of friction?
Wheels reduces the friction because to improve the speed of the machines. friction can be reduced with the help of the lubricants.
How does properly maintaining your bicycle increase its mechanical efficiency?
If it wasn't properly lubed before, then efficieny will be improved by lubricating. If it was properly lubed before, nothing much will happen.
Why friction should be reduced?
friction is a necessary evil for the man-kind although it has many advantages it also carries any dis-advantages with it which are discussed below :-. 1. it reduces the efficiency of any machine, as some of the energy is lost due to friction as heat energy.So the energy reaching the output would be {input energy - frictional energy} 2. it causes wear and tear of machines. 3. produces unnecessary heat.
What is one way friction affects a car?
Creates heat in the engine (friction of moving parts creates heat) Reduces efficiency (friction in the drivetrain, as well as air resistance, slows the car down) Causes the tires to wear out (friction between the road and the rubber causes the rubber to wear)
