The equation for the force of attraction for gravity looks similar to coulomb’s law: Force= k*m 1*m2 / r2. the only difference is the constant k (smaller for gravity) and the use of masses (m 1,m2) instead of charges. Why are both laws called an Inverse Square Law? Which force can only attract ot ...

History of electrochemistry
Electrochemistry, a branch of chemistry, went through several changes during its evolution from early principles related to magnets in the early 16th and 17th centuries, to complex theories involving conductivity, electric charge and mathematical methods. The term electrochemistry was used to describe electrical phenomena in the late 19th and 20th centuries. In recent decades, electrochemistry has become an area of current research, including research in batteries and fuel cells, preventing corrosion of metals, the use of electrochemical cells to remove refractory organics and similar contaminants in wastewater electrocoagulation and improving techniques in refining chemicals with electrolysis and electrophoresis.
