In any machine some work is wasted overcoming what?
In any machine, some work is wasted overcoming friction, which is the resistance caused by the rubbing of one object against another. This friction generates heat and sound, ultimately leading to a loss of energy efficiency in the machine. Minimizing friction through lubrication and proper maintenance helps reduce this wasted work.
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.
What work on a simple machine equals the output work the machine is said to be 100 efficient?
If a simple machine is 100% efficient, it means that the input work done on the machine is equal to the output work produced by the machine. In other words, all the energy put into the machine is completely converted into useful work without any energy being wasted.
If the blank work on a simple machine equals the output work the machine is said to be 100 efficient?
Yes, if the input work equals the output work, the machine is considered 100% efficient. This means that all the energy put into the machine is converted into useful work without any energy being wasted.
If the work on a machine equal the output work the machine is said to be 100 percent effentient?
Yes, that's correct. When the work input to a machine equals the output work, the machine is considered 100 percent efficient. This means that all the energy put into the machine is transformed into useful work without any energy being wasted or lost.

Why is work output by a machine always less than the work input?
It is usually unavoidable that some energy is wasted.
Why in a real machine is the output work always less than the input work?
That's related to the fact that in real machines, some energy is wasted.

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.

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.
What happens if you increase the efficiency of a simple machine?
Increasing the efficiency of a simple machine means that it requires less input work to produce the same output work. This results in less wasted energy and ultimately allows the machine to do more work with the same amount of input.
Is it easier to lift a 50 kilogram box straight up 8 meters or slide it up an inclined plane that is 20 meters long?
While lifting it straight up is harder, overall it is less work because you do not have to contend with the friction of the inclined plane. Overcoming that friction is work done which is totally wasted.While lifting it straight up is harder, overall it is less work because you do not have to contend with the friction of the inclined plane.

Who is greater the applied force or the force exerted by the machine?
That depends on whether the machine is designed to multiply force or distance. A machine designed to multiply distance will exert less force than was applied, and a machine designed to multiply force will exert the greater force over a shorter distance than force was applied to it. As for work, output work is always less than input work because some energy is lost in overcoming friction.
