What kind of energy conversions taking place when bouncing trampoline?
The same as in bounces in general. The kinetic energy gets stored briefly as elastic energy; this is then again converted to kinetic energy. As usual, some part of the energy is wasted.
Is it true that every time energy changes form some of it is given off as unusable?
In almost all energy conversions, a portion of the energy is wasted. Always remember that energy is never lost but is converted to a form that is of no use in the application. For example, an electric motor uses electrical energy to rotate but a portion of the electrical energy is converted to heat - it's wasted because heat doesn't help the motor to rotate but it's still a form of energy. A different example, that of a car engine. Energy that is released by the chemical reaction of burning gas is used to move the car forward. A significant amount of the energy is changed to heat. That is obvious when you feel the engine getting warm as it runs. The heat is mostly unusable so it is wasted. In most energy conversions, a proportion if the energy turns to heat so rarely is there a conversion that is 100% efficient. An exception is an electric heater. In this case, all the electrical energy that is delivered to the heater is turned into heat. What would be wasted energy in other applications is all useful so it can be considered to be 100% efficient.
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.
Explaine the law of conservation of mechanical energy?
This simply means that, as long as no mechanical energy is wasted or converted to other types of energy (and no other type of energy to mechanical energy), the total amount of mechanical energy doesn't change. Mechanical energy refers to the sum of kinetic and potential energy. Since energy losses and energy conversions do occur, this is not really a "law". In other words, the law of conservation of energy has not been known to be violated; conservation of mechanical energy is very easily violated.
Give an example of an energy conversion that produces unwanted forms of energy?
The heat a ball gives from the friction when someone kicks it
What is the largest amount of wasted energy in a transfer?
The situation really depends on the specific type of energy transfer. However, it is quite common that most of the wasted energy is converted into heat energy.
What is an energy conversion that produces an unwanted form of energy?
In most energy conversions, part of the energy will be converted to heat. That is usually unwanted, since energy is wasted, and the heat itself may also be problematic.
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.

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
Why is the final amount of usable energy in an energy transformation less than the original amount?
The idea here is that part of the original energy is wasted - converted to an unusable type of energy.

Why transmission is done on 11kv and 33kv?
High voltage reduces the amount of energy wasted in transmission lines.
