What form does machines wasted energy take?
Usually, much of the wasted energy takes the form of heat energy. However, part of the energy can also be in other forms, for example sound.
Why is a machine not 100 percent efficient?
Some energy (or power) is usually wasted. It is often possible to take measures to reduce it, but this can't be completely eliminated.Some energy (or power) is usually wasted.

Is it always easy to collect wasted energy and use it?
Once the energy is wasted, you can't convert it back to useful energy.Once the energy is wasted, you can't convert it back to useful energy.Once the energy is wasted, you can't convert it back to useful energy.Once the energy is wasted, you can't convert it back to useful energy.
How can a machine be useful if the output work is less than the input work?
Whatever we do, energy will be wasted. This can't be avoided; it's a fact of nature. Ideally, machines should be built to keep this waste energy as low as possible (although other criteria may also be important when building machines). Machines are useful for what they do for us. If, for example, we were to use our muscles to move things, some energy is wasted as well. In any case, we prefer to use a machine to do the moving, because of the convenience.
What is heated by the thermal energy wasted by a food mixer?
kinetic energy is wasted
How can you make machines more efficient?
Reduce or remove friction. Ensure that the energy going in is not wasted due to unnecessary work or heat.

What does wasted energy add too?
Wasted energy will increase the amount of useless, or unusable, energy, and reduce the amount of usable energy in the Universe. The wasted energy is related to entropy - one way to express the Second Law of Thermodynamics is to say that there are irreversible processes (in terms of energy), another is that "entropy increases". However, entropy is not energy; it is not measured in Joule, but in Joule/Kelvin. In any case, you might say that when energy is wasted, entropy increases.Wasted energy will increase the amount of useless, or unusable, energy, and reduce the amount of usable energy in the Universe.

What does simple machines change?
Simple machines such as pulleys, wedges, and levers reduce the amount of energy required to lift or move (heavy) objects.

kinetic 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.
How can you reduce the waste of energy?
Some ways to reduce how much energy is wasted would include, shutting off any lights that are not being used. Set thermostat to 78 and leave it. Turn the TV off and go for a walk.
Why does friction reduce the efficiency of machines?
Friction requires energy to overcome it. This causes loss of energy in the system. Loss of energy in a system, by definition, is a reduction of efficiency.
