When a machine is used to perform a task work output is always more than work input.?
This statement is not always true. In reality, some energy is lost in the form of heat, sound, or friction while a machine is being used, meaning that the work output is often less than the work input due to energy losses within the system. This concept is known as efficiency, and it is a measure of how well a machine can convert input energy into useful output energy.

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.
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.
When a machine is used to perform a task work output is always what than work otput?
When a machine is used to perform a task, the work output is always less than the work input. This is due to factors such as friction, heat loss, and other inefficiencies in the machine, which result in energy being lost during the conversion process.
How are the input and output forces of the parts of a compound machine relate?
In a compound machine, the input force is the force applied to the machine, while the output force is the force exerted by the machine to do work. The relationship between input and output forces depends on the configuration of the machine. In general, the output force of a compound machine is the combined output forces of its individual parts, which may result in a mechanical advantage that allows the machine to perform work more easily.
Is it true that when a machine is used to perform a task work output is always more than work input?
Not necessarily. In reality, machines are not 100% efficient and there are losses due to factors such as friction, heat, and other inefficiencies. As a result, the work output may not always be more than the work input when using a machine.

What is a comparison of a machine's work output and work input?
Output is always greater than input. The output is multiplied from input.

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 in an output force?
In a closed system in the "real world" in which we live, there are losses associated with friction and other actions. These forces "take energy" from the system between its input and output. When we apply force to the imput of a system, some is lost as the force is transferred through that system. That means that the output force we observe will always be a bit less than the input force. A transmission in a vehicle is a classic example of the idea that there are losses between the input and the output of a system. The input from the engine will always be a bit greater than the output at the tailshaft (or axles for a transaxle) due to losses within the transmission.
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.
What is the definition of output and input work?
Work Input- The work done on a machine as the input force acts through the input distance. Work Output - The work done by a machine as the output force acts through the output distance (What the machine does to the object (dependent on the force) to increase the output distance).
What is the reason a machine's output work is always less than the input force?
Entropy.
The output work of a machine compared to it input work is the of the machine?
Output(input), or O(i)
