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 heat the most common form of wasted energy?
Heat energy is the most wasted form of 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.
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.
What is useful and wasted energy?
Useful energy is energy that can be converted to any other type of energy. Wasted energy is no longer available to be converted - usually because it got spread out too much, or because it got converted to heat. Heat can be partially, but not completely, converted to other types of energy.

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 is heated by the thermal energy wasted by a food mixer?
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.
Wasted energy produced by motor bike?
Noise and heat is wasted energy from motorcycles.
What is the usefull and wasted energy in a hair dryer?
Sound energy from the hair dryer is wasted.
How do you conserve and use geothermal energy properly?
no, because we all waste geothermal energy by driving cars then all that energy is wasted.
Why radio is an sound energy?
Because it is making sound. A radio also gives off heat energy that is wasted
