How is electrolysis used in order to prevent materials from corrosion or rusting?

We use electrolysis to prevent a material from rusting,

The metal forms a coating around the material and hence prevents any contact between the material and the environment

This process also gives us the physical strength of the material and the aesthetic properties of the coated metal

the metal commonly used to coat the object is Zinc and the process is called galvanisation

another example of kinetic energy would be,

kinetic energy   >     moving energy

hope that !                                         : )

probably not if net force is zero
