Why is a machine is never 100 efficient?
A machine can never be 100% efficient because some energy is always lost as heat due to friction, air resistance, and other factors. These losses result in the machine not being able to convert all input energy into useful output energy.
The efficiency of a machine is always less than 100 percent because?
some energy is always lost to factors like friction, heat, and sound during the operation of a machine, reducing its efficiency below 100%.
What is the relationship between friction and efficiency of a machine?
The relationship between friction and the efficiency of a machine is when friction increases, efficiency decreases, and vice versa. That is why you can never have 100% efficiency, because there is always at least a little friction. They are inversely proportional, meaning, higher friction equals less efficiency.
Why is the output energy of a machine always less than the input energy?
The output energy of a machine is always less than the input energy due to energy losses from factors such as friction, heat, and inefficiencies in the system. These losses result in some of the input energy being transformed into forms that are not useful for the intended function of the machine.
If the efficiency of a machine is always less than 1 why is the principal of conservation of energy still obeyed?
The principle of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another. Even though a machine's efficiency is always less than 1 (due to energy losses like friction and heat), the total energy input should still equal the total energy output, ensuring that energy is conserved.

Why is a the mechanical efficiancy of a machine less than 100?
Because, due to friction, there will always be a percentage of the energy lost through wasted heat.

What energy is lost in machine?

Why is it not possible to construct a perpetual-motion machine?
Some energy will always be lost due to different factors such as friction.
Why is friction a bad thing?
Friction isn't always bad, but when engineers try to avoid or reduce friction, it is because of the energy lost due to friction.
Why have attempts to create a perfectly energy efficient machine been unsuccessful?
The input energy can never equal the energy outputted by any machine because energy is always lost in the process. Where that energy is lost is dependent on the machine, but some easy examples would be heat (namely due to friction), sound, and radiant (light).
Which is not a source of energy loss in a machine?
Friction is not a source of energy loss in a machine.
Why it is important for you to reduce friction on compound machine?
Reducing friction on a compound machine is important because it helps improve the efficiency of the machine by minimizing the energy lost due to friction. Lower friction also translates to less wear and tear on the machine's components, ultimately extending its lifespan and reducing maintenance needs. Additionally, decreased friction can enhance the overall performance and precision of the machine's operations.
