For example:
Frame and door sliding against each other.Rubbing of hands together to generate heat. We notice that the surface is smooth in the above examples, but when the same object is observed more closely through a microscope, it may seem that even the smooth-appearing object has rough edges.
Methods to reduce friction:
Some methods to reduce friction are provided below:
When objects are rolled over the surface, the friction between the rolled object and the surface can be reduced by using ball bearings.Using lubricants such as oil or grease can reduce the friction between the surfaces.By polishing the surface, polishing makes the surface smooth and friction can be reduced.
