What else can I help you with?
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 cant a machine put as much energy out as you put in?
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.
Why does reducing the friction of a machine increase it's efficiency?
Reducing friction in a machine decreases the amount of energy lost as heat, making the machine more efficient. This means that more of the input energy is converted into useful work or output, increasing the overall efficiency of the machine.
What comparison of work the machine does with energy it uses to do the work?
The work done by a machine is directly related to the amount of energy it uses. Machines convert the input energy into work output, with the efficiency of this conversion determined by factors such as friction, heat losses, and mechanical losses within the machine. The more efficient the machine, the more work can be accomplished with the same amount of energy.
Can you get more energy out of machine than that is put in?
No, according to the law of conservation of energy, energy cannot be created or destroyed. Therefore, it is not possible to get more energy out of a machine than is put into it. Any energy output will always be equal to or less than the energy input.
What is energy feeds?
An energy feed is a food source that gives extra energy to those who eat it, allowing them to expend more energy when needed.
Does a plane consume more or less fuel with a headwind?
It would consume more fuel - as it would need to expend more energy to fight against the headwind.
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.
Why do you need to conserve the amount of energy you use?
If you are trying to lose weight, no you should expend more of your muscle energy. Otherwise, yes. Additional energy expenditures force us to burn fossil fuels.
Which cardio machine will help me lose weight the fastest?
You will burn more Calories the more energy you expend, So running will make you lose weight faster than walking and diet also plays a very impotant part, staying away from too much fats and sugar would help probably more and watching your Calorie intake.

How do we get fat?
By consuming more calories than we expend.

What organism contains the greatest amount of energy in an energy pyramid?
The lowest; all others expend it at some point, which makes it leave the pyramid/food chain. << The base (producers) because that is the level where energy is first fixed to the ecosystem. ALL levels expend more energy than they fix. >
Can you get more energy out of machine than that is put in?
No, according to the law of conservation of energy, energy cannot be created or destroyed. Therefore, it is not possible to get more energy out of a machine than is put into it. Any energy output will always be equal to or less than the energy input.
