Can a simple machine put out more energy than is put into it?
NO. No system can put out more Energy than is put into it. That would violate the 2nd Law of Thermodynamics. However, a simple machine, like a lever can put out more Force than is put in.
Why will you never get more work out of a machine than you put into it?
This is known as the principle of conservation of energy, where the total amount of energy put into a machine is equal to the total amount of work the machine can output. Due to factors like friction and heat, some input energy is always lost, making it impossible to get more work out of the machine than what was initially put in.
Why is it impossible for a machine to give you more energy output than the amount of energy put into it?
It is impossible due to the principle of energy conservation, which states that energy cannot be created or destroyed, only transferred or transformed. Therefore, any machine or system will always output less energy than the amount of energy put into it. This limitation is known as the efficiency of the machine.
Under certain conditions it is possible to get more work out of a machine than you put into it True or false?
True, it is possible to get more work out of a machine than you put into it due to efficiencies in the machine's operation. This is based on the principle of energy conservation where energy input may be converted to a different form that allows for increased work output.
Does the work you put into a machine the same work you get out?
No, due to factors such as friction, inefficiencies, and energy losses, the work you put into a machine is typically more than the work you get out. This difference is known as mechanical efficiency.

In what way is a machine subject to the law of energy conservation?
The law of conservation of energy was never found to be violated. The relevance for a machine is that a machine can not produce more energy than is put into the machine.

Does Pascals principle provide a way to get more energy from a machine than is put into it?
Yes

Why is the amount of that a machine does is less than the amount put into the machine?
In such a machine, the remaining energy is wasted to friction

No, due to factors such as friction, inefficiencies, and energy losses, the work you put into a machine is typically more than the work you get out. This difference is known as mechanical efficiency.
Is a machine physically possible that has an efficicency greater than 100 percent?
No. In fact, in the real world, a machine with an efficiency of only 100%isn't even physically possible.But why isn't an efficiency greater than 100% physically possible ?Efficiency means (output energy) divided by (input energy) .If efficiency is greater than 100%, that means output/input is greater than ' 1 ', andthat means that you get more energy out of the machine than you put into it.Where could that extra energy come from ? Remember the law of conservationof energy ? It says that energy is never created or destroyed. So you can't getmore energy out of a machine than you put into it, and output/input can't bemore than ' 1 '.It sure would be nice though: Put some energy into the machine to get it started,and then just sit back and watch it run. Out of the end comes more energy thanwhat it takes to run the machine, so you split up the energy that comes out. Youtake just enough to keep the machine running, and you put that much back into it.Then you still have some energy left over, so you take that part and use it to heatyour house, or pump water out of the well, or generate electricity to light your Christmaslights, or sell it. You'd never need to buy any more energy, or burn any coal or oil orwood or uranium, because you'd get enough out of the machine to keep it runningplus more energy to use or sell.
Why does Pascal's principle provide a way to get more energy from a machine than is put into it?
IT CERTAINLY DOES NO SUCH THING! You can't get more energy out of a machine than you put in, except in the short term. (If some energy happens to be stored in a machine, you can get it out.) Such a thing would violate the Law of Conservation of Energy, which seems to be a fundamental law of nature. No violation of this law has been found so far!Pascal's principle allows to increase the output FORCE compared to the input FORCE, but you must be careful not to confuse FORCE with ENERGY. (They don't even have the same units. Energy is related to work, and work is, basically, force x distance.)
Why can't mechanical efficiency be over 100 percent?
The mechanical efficiency can't be over 100% because a type of energy is always lost. For example, it can be lost as heat, sound or even light. When you use a light bulb, it produces light, but heat is lost in the process. See what I mean! In most cases, heat is lost due to friction. the work put out by a machine is always less than the work put into a machine to do the work. Therefore no machine is 100% efficient. As well.... Efficiency is (power out/power in) x 100. To get an efficiency of *more* than 100%, the machine must give more power out than is put in. No machine has ever been demonstrated that does this, and until someone can show this result (power out *more* than power in), we know that any machine has an efficiency less than 100%.
Why is a perpetual motion machine not possible?
It's not possible because it would violate one or both of the laws of thermodynamics. The first law of thermodynamics says that you can't create energy from nothing, or to out it another way, you can't get more energy out of a machine than you put into it. The second law says that no machine is 100% efficient. You must actually get less energy out of a machine than you put into it. The laws of thermodynamics apply to the entire universe and all bodies within it, including alleged perpetual motion machines.
