We use energy everyday to power our electronics. The electricity we used is generated by different energy sources. (4) such as coal, is most often used to produce electricity. Burning coal can create pollution in our environment, so other sources of energy should be used. The use of running water in 15 is an example of using a (6). source to help reduce the amount of pollution Other sources that prevent pollution include sun, wind, and even (7), which makes these options much more​

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

bradykinin is a physiologically and pharmacologically active peptide of the kinin group of proteins, consisting of nine amino acids.
