What are the ten good uses of friction?
fricion can be used in machines, brakes in a car, sandpaper, lighting a match and rubbers.
Is friction good for machines?
Some machines need friction to operate. Brakes, grinders, traction wheels, and others all rely on friction to work. In other cases, friction is bad. electric and fuel-fired powerplants for example, are all designed so as to minimize friction. That's why the lubricant industry exists!
Why is oil used in many large machines?
Oil is used as a lubricant in many large machines in order to reduce the friction between two or more moving parts.
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.
Why noise is produced in machines?
Noise is produced in machines due to friction.
What can make machines more efficient by reducing friction?
the relationship between them is that the machines have friction that makes the machine goes

What is machines that experiences friction called?
brakes
How do we decrease friction in machines?
You provide lubrication.
What are disadvantages of heat produced by friction in machines?
energy used for the machine will get lost as heat .machine parts will get worn out.
