To calculate the total input, you need to sum up all the individual inputs or factors that contribute to the overall system or process. This can include costs, resources, time, or any other relevant inputs that are part of the equation. By aggregating all these individual inputs, you can determine the total input for the given scenario.

How is a machine's efficiency of a calculated?
Efficiency = useful output power / input power
The efficiency that requires 100j of input to do 35 j of work?
I believe the answer is 35%. Since the formula for energy = useful work / total work input, you would then plug 35 j into the useful work and 100 under the total work input. You divide that and you get .35. Then, you multiply .35 by 100, and you get 35%.
How do you calculate the mechanical efficiency?
Mechanical efficiency is calculated by dividing the useful work output by the total energy input, and then multiplying by 100%. The formula for mechanical efficiency is (Useful work output / Total energy input) * 100%.
Is the efficiency of a machine is 60 the percentage of work input used to overcome friction?
No, efficiency of a machine is a measure of how well input energy is converted into useful output work, and is calculated as useful work output divided by total work input. The percentage of work input used to overcome friction would be related to the frictional losses in the machine, not the overall efficiency.
Why is work output always less than work input?
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.

What is the relationship between work input and work output with reference to the law of conservation of energy?
According to the law of conservation of energy, energy cannot be created or destroyed, only transferred or transformed. This principle applies to work input and output, as the total work output of a system will always be equal to the total work input. Any work done on a system is transformed into some form of energy that is then used to perform the work output.
Is the efficiency of a machine is 60 the percentage of work input used to overcome friction?
No, efficiency of a machine is a measure of how well input energy is converted into useful output work, and is calculated as useful work output divided by total work input. The percentage of work input used to overcome friction would be related to the frictional losses in the machine, not the overall efficiency.
Why is work output always less than work input?
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.
Which factor increases as the efficiency of a machine increases?
The output work done by the machine increases as the efficiency of the machine increases. This is because efficiency is the ratio of useful work output to the total work input, so as efficiency increases, more of the input work is converted into useful output work.
What is the efficiency of an engine that gives off thermal energy?
The efficiency of an engine that gives off thermal energy is determined by the ratio of the useful work output to the total energy input. It can be calculated using the formula Efficiency = (Useful work output / Total energy input) x 100%. A higher efficiency indicates that the engine is converting more of the input energy into useful work.
Can you make the work output of a machine greater than the work?
No, the work output of a machine cannot be greater than the work input. According to the law of conservation of energy, the total amount of energy remains constant in an isolated system, meaning the work output of a machine cannot exceed the work input.
How does friction affect the equality between work input and work output in real situations?
Work Input = Work Output + Work done in overcoming friction.Therefore Work Input > Work Output.
Which shows relationship between work input and work output?
The relationship between work input and work output is defined by the efficiency of a system. Efficiency is a measure of how well a system converts input work into output work and is calculated as the ratio of output work to input work. A higher efficiency indicates a more effective conversion of work input to work output.
What means work output divided by work input?
Work output divided by work input is known as the efficiency of a system. It represents the ratio of useful work output compared to the total work input required to perform a task. A system with high efficiency is able to convert a larger portion of input energy into useful output energy.
