Some work is lost due to friction. This energy is normally released as heat.

Due to conversion of energy to heat
Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.
No, there is not such thing as an ideal machine; it's just an idea.
It is always less than 100% Theoretical machines can have efficiencies of 100% but in practice there is always some energy loss Efficiencies of more than 100% are not allowed by the laws of thermodynamics!
Output work is always less than input work.
input
It is the output energy compared to the input energy. This will always be less than 100%
if a machine is not efficient, it cannot fully utilise its performance. actual performance = efficiency x possible performance efficiency = actual performance / possible performance efficiency is always a decimal number less than 1, as no machine is perfect in terms of efficiency
The relationship between friction and the efficiency of a machine is when friction increases, efficiency decreases, and vice versa. That is why you can never have 100% efficiency, because there is always at least a little friction. They are inversely proportional, meaning, higher friction equals less efficiency.
no machine has one
so wut exactly is ur question?
Efficiency is the ratio of the energy converted into useful work by the machine to the energy supplied to the machine. Certainly it will not be possible to convert all the energy supplied into useful work because of wastage of energy due to so many reasons. So efficiency will be always less than 1. As the efficiency becomes more the loss would become less. Hence it is desirable.
please rephrase ur question so that it can be understood
