The cause behind this phenomena that so many shop and maintenance trainers can't explain is caused by the Van der Waals force. This has only been proven to be factual in the last decade after better understanding of quantum dynamics. This is due to attraction or the opposing forces at the molecular level. Years ago this was one of those phenomena that no one could explain and trainers would ask there students to demonstrate what seemed to be magic. Only through test that are able to be performed now through advanced technology that this has proven to be fact.

Why can you only see yourself in smooth and polished surfaces?
You can see yourself in smooth and polished surfaces because the surface is clean and not blurry. Also, you can't see yourself in certain smooth and polished surfaces, such as tan desks.
Does friction depend on the types of surfaces involved and how hard the surfaces push together?
Friction does depend on the types of surfaces involved and how hard the surfaces push together. Friction would be very minimal if the surfaces were smooth and not pushing together too hard.
How is friction reduced on modern cars?
By lubrication and using polished surfaces and avoiding the striking mechanism of 2 parts in an engine...
What is static electricity caused by?
socks taken from a clothes dryer stick together
What surfaces create most friction?
a perfectly polished surface creates the most, follower by a rough surface, which is the more usual case.
Why do room heaters have bright polished surfaces?
Bright, polished surfaces reflect heat more efficiently.
Why can you only see yourself in smooth and polished surfaces?
You can see yourself in smooth and polished surfaces because the surface is clean and not blurry. Also, you can't see yourself in certain smooth and polished surfaces, such as tan desks.
What is meant by the term polished surfaces?
Of what
What surfaces does uv light reflect off of?
Polished aluminum
Can you give some sentences using the word cohesive?
Water molecules are both cohesive and adhesive: they can stick together or stick to other surfaces.
The polished surfaces of rock which are a rasult of rock moving against rock along a fault are know as?
slickensides are polished surfaces of rock which are a rasult of rock moving against rock along a fault
A typical property of a metal surfaces when freshly cut or polished?
Shiny.
What are the polished surfaces of rock from rock moving against rock?
slickenslides
What is the definition of microwelds?
A microweld is an area where the microscopic bumps on two surfaces stick together. Microwelds are the source of friction.
How does PVA glue stick wood together?
- PVA, white or yellow glue soaks into porous surfaces, then dries as it's carrier solvent evaporates. The substance left after evaporation has become hard and bonds the 2 surfaces together.
What type of erosion can make pits and rocks and produce smooth and polished surfaces?
It is abrasion
