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.
Is the work output always less than the work input when a machine is used to perform a task?
No, the work output is not always less than the work input when a machine is used. In an ideal scenario, the work output from a machine can be equal to or even greater than the work input, though in practice some energy is always lost due to factors such as friction and heat.
Why is the output energy of a machine always less than the input energy?
The output energy of a machine is always less than the input energy due to energy losses from factors such as friction, heat, and inefficiencies in the system. These losses result in some of the input energy being transformed into forms that are not useful for the intended function of the machine.
How does the output work compare to the input work for a machine that has an efficiency less than 100?
For a machine with efficiency less than 100%, the output work will always be less than the input work. This is because some of the input work is lost as waste energy due to factors like friction, heat, or other inefficiencies in the machine. The efficiency of a machine is a measure of how well it converts input work into useful output work.
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.
What is the reason a machine's output work is always less than the input force?
Entropy.
Why in a real machine the output work is always less the input work?
In a real machine, part of the energy (or power) is always wasted.

What is meant by efficiency of a machine?
It is the output energy compared to the input energy. This will always be less than 100%
When a machince is used to perform a task work output is always what than work input?
When a machine is used to perform a task, the work output is always less than the work input. This is because some of the input work is lost due to factors such as friction, heat, and inefficiencies in the machine. This is known as the principle of conservation of energy.
Why is work output by a machine always less than the work input?
It is usually unavoidable that some energy is wasted.
How is the work output of a machine related to it's work input?
In an ideal universe, where there are no friction or heat transfer losses, work out = work in. In our universe, however, work output is always less than input. How much less depends on the efficiency of the machine's design.
Is it true that work output of a machine is always less than work input because of energy lost due to friction?
Yes, it is true. Due to factors such as friction, heat generation, and other inefficiencies in the machine, some of the input energy is always lost to the surroundings rather than being converted into useful work output, resulting in the work output being less than the work input.
