This is known as the principle of conservation of energy, where the total amount of energy put into a machine is equal to the total amount of work the machine can output. Due to factors like friction and heat, some input energy is always lost, making it impossible to get more work out of the machine than what was initially put in.
What else can I help you with?
Why is it impossible for the output work of a machine to be greater than the machine's input work?
The output work of a machine can never be greater than the input work because of the law of conservation of energy, which states that energy cannot be created or destroyed in an isolated system. Any energy input into a machine must be accounted for in the output work, so the output work cannot exceed the input work.
Does the work you put into a machine the same work you get out?
No, due to factors such as friction, inefficiencies, and energy losses, the work you put into a machine is typically more than the work you get out. This difference is known as mechanical efficiency.
Under certain conditions it is possible to get more work out of a machine than you put into it True or false?
True, it is possible to get more work out of a machine than you put into it due to efficiencies in the machine's operation. This is based on the principle of energy conservation where energy input may be converted to a different form that allows for increased work output.
Can the work output of a machine ever be greater than the work output?
No, the work output of a machine cannot be greater than the work input. This violates the principle of conservation of energy, which states that energy cannot be created or destroyed, only transferred or converted. Any machine that claims to produce more work output than its input is operating outside the laws of physics.
What is the work output of a machine never equal to the work input?
The work output of a machine will never be equal to the work input due to efficiency losses such as friction, heat, and other factors that result in energy being wasted rather than converted fully into useful work. This phenomenon is known as energy loss or inefficiency.
If machine A performs work in twice as much time as machine B then machine B will use more what than machine A?
Machine B will use more power.
In a compound machine made up of two simple machines how is the work output of the first simple machine related to the work input of the second simple machine?
The work ouput of the second machine will usually be more than the work input of the first machine.
What voltage of popcorn machine will work best?
The popcorn machine is nothing more than a heating element and fan. Most popcorn matching run on 110 v outlets. You should never plug something into an outlet that was not designed for it.

How do you find the efficiency of a simple machine?
The efficiency of a machine is found by considering the useful energy or work that comes out of it, and dividing this by the work that you put into it. Multiply by 100 to get the answer in terms of percentage. You should never get more than 100% efficiency, or 100%, since energy will be lost (to heat caused by friction for example).
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
How much more efficient is the hotpoint aqualtis than normal washing machine?
30% i work for them
What is measured by the power of a machine?
Power is the amount of work a specific machine can do over a period of time. Work is the product of force and the distance an object travels as a result of that force. A more powerful machine can effect changes in velocity of an object more rapidly than a less powerful machine.
