Whatever we do, energy will be wasted. This can't be avoided; it's a fact of nature. Ideally, machines should be built to keep this waste energy as low as possible (although other criteria may also be important when building machines). Machines are useful for what they do for us. If, for example, we were to use our muscles to move things, some energy is wasted as well. In any case, we prefer to use a machine to do the moving, because of the convenience.

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.


Is A measure of how well a machine operates is its efficiency?

Efficiency is indeed a measure of how well a machine converts input energy into useful output. It is calculated by dividing the useful output by the total input. Higher efficiency indicates better performance and less wasted energy.


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.


If the output work of a simple machine is than input work the machine is said to have less than 100 percent efficiency?

No, a simple machine with less output work than input work is said to have less than 100 percent efficiency. Efficiency is a measure of how well a machine converts input work into output work, with 100 percent efficiency meaning that all input work is converted to useful output work.


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 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 does the term efficiency of machine' means?

The efficiency of a machine refers to how well it converts input energy into useful work output. It is a measure of how effectively the machine minimizes waste and maximizes its output relative to its input. Higher efficiency means less energy loss during the machine's operation.


In a machine work output is less than work input because some energy is converted into thermal energy True or false?

True. In a machine, not all of the input work is converted into useful output work. Some of the input work is lost as thermal energy due to friction, inefficiencies, and other factors. This is why the output work is always less than the input work.


Explain why the amount of work that a machine does is less than the amount put into the machine?

The amount of work that a machine does is less than the input work due to energy losses in the form of friction, heat, and inefficiencies in the machine's operation. These losses result in some of the input work being dissipated and not translating fully into useful output work performed by the machine.


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.


How the output work compares to the input work in a machine?

I would say that the output would be less. What would you think? Actually it matters what machine your talking about but hopefully ur output work would be more then your input work because that would mean the machine is doing more. This would mean its more efficent


What stronger work output or work input?

In theory, work output might be equal to work input; that would be 100% efficiency. In practice, the output of a machine will be less than the input; i.e., some energy will be lost.In theory, work output might be equal to work input; that would be 100% efficiency.
