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.

Why is the work output of a machine always less than the work input?

The work output of a machine is always less than the work input due to energy losses in the form of heat, friction, and other inefficiencies. These losses result in some of the input work being converted into forms other than useful output work, leading to a decrease in efficiency.


Why is the output work always less than the input work for a real machine?

The output work is always less than the input work for a real machine due to factors like friction, heat loss, and inefficiencies in the machine's components like bearings and gears. These losses result in energy being dissipated as heat rather than converted entirely into useful work, leading to a decrease in the amount of work obtained from the input energy.


The efficiency of a real machine?

Efficiency is equal to the ratio of work input to work output; for an ideal machine this ratio is equal to 1 or 100%. For a real machine this ratio is always less than 1 because some of the work input is used to overcome mechanical friction within the machine which does not contribute to the work output of the machine.


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.


Work input equals work output is what type of machine?

A machine that has work input equal to work output is known as an ideal machine. This means that the machine is 100% efficient, converting all the input work into useful output work without any losses. Ideal machines only exist in theory, as real machines always have some energy losses due to factors like friction and heat.
