That means that some energy is wasted. For example, it is quite common for part of the input energy to be converted into useless heat.
A drastic example is a traditional incandescent light bulb. Something like 5% of the energy gets converted into visible light. The remainder is radiated mainly as infrared - that is, heat radiation.
That simply means that some energy is lost, due to friction and other causes.
To find 10 percent less than 2500, you first calculate 10 percent of 2500 by multiplying 2500 by 0.10, which equals 250. Then, subtract 250 from 2500 to find the result. Therefore, 10 percent less than 2500 is 2250.
Any percent less than 100.
13 is 162.5 percent of 8 .
6.7 is more than 67 percent, as it is the same as 670 percent.
No, a simple machine with less output work than input work is said to have less than 100 percent efficiency. Efficiency is a measure of how well a machine converts input work into output work, with 100 percent efficiency meaning that all input work is converted to useful output work.
Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.
input
If loads varies then efficiency is less steeply than efficiency. This is taught in science.
so wut exactly is ur question?
Then the output work is less than the input work. That description applies to every machine that has ever been built or will ever be built.
It is always less than 100% Theoretical machines can have efficiencies of 100% but in practice there is always some energy loss Efficiencies of more than 100% are not allowed by the laws of thermodynamics!
Friction between moving parts can cause energy loss in a simple machine, reducing its efficiency below 100 percent. Additionally, external factors such as air resistance or other forms of resistance can also contribute to energy losses in a simple machine.
some energy is always lost to factors like friction, heat, and sound during the operation of a machine, reducing its efficiency below 100%.
Losses of energy within the machine- some of the energy is used up by friction, and converted to heat. There is also the matter of efficency of a machine. The less efficent, the more power you must put in to get the same output.
less
Yes, it is true. Due to factors such as friction, heat generation, and other inefficiencies in the machine, some of the input energy is always lost to the surroundings rather than being converted into useful work output, resulting in the work output being less than the work input.
