Why is it that efficiency of a machine is less than 1?
The efficiency is always less than one because some of the energy is always useless for what you want. Most wasted energy eventually turns into heat. therefore the efficiency is like a percentage with 1 being 100% a device can't be 100% efficient as some energy is wasted. To work out the efficiency of a device you need to do the total useful energy produced divided by the total energy that is inputted into the device
Why is efficiency less than 1?
The Law of Conservation of Energy states that energy can't be created or destroyed. Thus, efficiency is 1 (i.e., 100%) if there is a perfect energy conversion. Since this is usually not the case, and some energy is wasted, the efficiency of most energy conversions is less than 100% (or less than a factor of 1).
Is 1 kilogram less than or greater than 1 pound?
less than
Is 1 greater than or less than 9.7?
1 is 8.7 less than 9.7
Is 0 less than 1?
Yes, 0 is less than 1.
How does effieciency of the machine affects it's performance?
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

Describe why a high-efficiency machine is more desirable than a low-efficiency machine?
A high-efficiency machine consumes less energy to perform the same task as a low-efficiency machine, resulting in lower operating costs and reduced environmental impact. Additionally, high-efficiency machines often have longer lifespans and require less maintenance, leading to overall cost savings and improved reliability.
How do you prove that the efficiency C arnot is greater than 1?
You don't. Such an efficiency can be less than 1, but it can't be greater than 1.
In a machine work output is less than work input because some energy is converted into thermal energy.?
Yes some energy is lost in the form of heat and so the efficiency of the machine is always less than 1 ie 100%
In a machine work output is less than work input because some energy is converted in thermal energy?
Yes some energy is lost in the form of heat and so the efficiency of the machine is always less than 1 ie 100%
In a machine is work output less than work input because some energy is converted into thermal energy?
Yes some energy is lost in the form of heat and so the efficiency of the machine is always less than 1 ie 100%
In a machine work output is less than work input because some energy is converted into thermal energy?
In a machine, the work output is always less than the work input due to energy losses, primarily in the form of thermal energy. This loss occurs due to factors such as friction, air resistance, and other inefficiencies within the machine. The difference between the work input and work output is known as the efficiency of the machine, which is a measure of how well it converts input energy into useful work output.
The mechanical advantage of a machine is always greater than 1?
False. The mechanical advantage of a machine can be greater than, equal to, or less than 1, depending on the type of machine and how it is designed.
Is a ideal machine has an efficiency of less than one equal to one greater than one?
ideal machines have mechanical efficeincy equal to 1 (100% efficient) since efficiency is the ratio of the power output to the power input
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.
