Motion and Frame of Reference Mrs. Gibson Physical Science
Motion • Change in Position in a certain amount of time
To describe motion it must be compared with something assumed to be stationary - Background - Object (s)
The Background or Object is called the … FRAME OF REFERENCE Frame of Reference (F of R) depends on your position of observation and the type of movement you are observing or experiencing, ex: movie set background http://www.teachertube.com/viewVideo.php?video_id=58178&title=Frame_of_Reference__3 See Online Java Applet:http://ww2.unime.it/weblab/mirror/ntnujava/relativeVelocity/relativeVelocity.html
KEY POINTS • No F of R is more correct. • All motion is described with a F of R. • The most common F of R is the Earth as a background.
