What role does friction play in energy transformations?
In many cases, energy is wasted due to friction - meaning that useful energy is converted into unusable energy.
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 w is energy that is not useful?
Waste energy.
How is energy efficiency determined?
You divide useful output energy by the input energy. Or equivalently, useful output power by input power.
What are useful and non-useful energy transfers in the production of electricity using coal?
Useful is the actual production of electricity. Non-useful -- unused heat energy released into the environment.

If electrical energy goes into a light bulb what useful energy comes out?
The useful energy that comes out is light energy. Heat energy is also produced but is not useful

What we energy that is not useful?
Waste energy
A comparison of amount of energy before a conversion with the amount of useful energy after a conversion?
Usually, the amount of useful energy after a conversion will be less than the original energy. In no case can it be more.Usually, the amount of useful energy after a conversion will be less than the original energy.

What is a 2nd law of energy?
You must be referring to the two Laws of Thermodynamics. Stated in terms of energy: 1. The First Law of Thermodynamics is the Law of Conservation of Energy, meaning that energy can not be created or destroyed. 2. However, useful energy is continuously being converted into unusable energy. This is irreversible. This is the Second Law of Thermodynamics.
