Description: Based on the textbook Physics, by the Physical Science Study CommitteeDirector, Richard Leacock; photographer, Abraham Morachuik; editor, Jack KaufmanDemonstrates through a variety of experiments the distinction between an inertial and noninertial frame of reference, and the appearance of fictional forces in a non-inertial frame. Opens on a scene in which what at first appears to be down is gravitationally up, and a sequence in which it is difficult to identify wheather the foreground or background is in motion. Using slow-motion photography the path traveled by a ball dropped from a stationary and constant velocity cart is studied from both fixedand moving frames of reference. Real forces operate in inertial frames of reference; however, "fictional forces" seem to operate in accelerated frames of reference. Several additional examples of accelerated frames of reference are presented using a large rotating turntable including the Foucault pendulum. Explains that fictional forces are required in accelerated frames to prevent laws of physics from changing
