Difference between friction and science friction?

Answer 1

Are you asking about friction or fiction?

Friction is a physics term to describe a force to keep adjoining bodies from sliding.

Fiction is a term used to describe literature that is "made up".

Fiction can encompass a number of subjects including romance, history, westerns, law, fantasy, and Science Fiction. Thus, the term of Science Fiction would be a subset of all Fiction.

There is some overlap between Science Fiction and Fantasy, and they are often classified together.

Science Fiction almost always deals with possible events in the future. This can be either near, or distant future. It usually deals with technology that is plausible in the future, although whether or not the technology will be invented is unknown. We currently have no Faster than Light or WARP technology, yet it is a favorite of space stories. However, the communicators of the early Star Trek movies are far less sophisticated than the average cell phones of today. And even Lt. O'hara's ear bud looks amazingly similar to the blue-tooth devices that are available today.

Most other forms of fiction deal with technology that is or was available at the time the show is set in, and technology plays a much less prominent role in the stories. However, some spy stories often will also include an element of science fiction.
