How is mechanical energy conserved?
It isn't. Sooner or later some mechanical energy will be wasted and converted to heat. It is also possible to convert other types of energy into mechanical energy.It isn't.

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.
What makes an energy transformation inefficient?
Energy can get wasted through several means. One of the most obvious ones is friction. However, entropy also increases - and energy therefore gets wasted - in other ways; for example, when there is a heat transfer between two objects that are at different temperatures; when eddies are produced in a water current (or electrical current); when electrical current gets converted to heat in a resistance; and through several other means. Quite often, the intention of an energy transformation is to produce one type of energy (for example, light in a light-bulb); but additional (undesired) types of energy are produces as well, quite often heat.
What is the result of wasted energy?
Well, thermodynamics is the science that studies this. According to the the first law of thermodynamics, all energy in all forms are conserved. The main types of energy we consider is kinetic, potential and internal energy. You may not be familar with Internal energy but it is another form of energy that we lump the energy of chemical bonds and kinetic and potential energies (ON THE MOLECULAR LEVEL) into it. Internal energy is proportional to the temperature of the object.

How is mechanical energy better than thermal energy?
Mechanical energy can be easily converted to other types of energy. Thermal energy is, to a great extent, wasted energy - it can no longer be converted to other types of energy.
Can electrical energy be transformed into many different types of energy by devices and components?
Yes.
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.
What types of electrical devices use the most energy?
the most common is light and heat

Does a low-energy light-bulb create more heat in a room?
Compared to other types of light-bulb, energy-saving light bulbs will create less heat. This is because any wasted energy is converted to heat.
Why sould you save energy?
Saving energy is really important because if we don't save energy and it all gets wasted it can not be renewed . Some types of energy can be renewed.Try turning off the light when your not using it try taking a walk to school if you can there are alot of explanations on why you should save energy.
Whats inside a battery?
Inside a battery, stored chemical energy is released as electric energy which can then power devices. This energy is stored in different ways in different types of batteries.
What elements are used in a factory?
Common elements are electric energy, water, vehicles, computers, workers, diversified types of machines, electronic devices, illumination, small mechanical devices and so on.
Name the 3 types of storage devices?
name 3 types of permanent storage devices
What is the difference among different types of switching devices?
The difference among different types of switching devices is in the features and the functions that they have. The two main types are packet switching and circuit switching devices.
