This program on physics is the last of five programs in the science section of the GED Connection series, which helps prepare students for the GED exam. Physics is the study of forces that move things. Matter is anything that takes up space or has a mass. The program features guests of various disciplines who explain specific applications of physics concepts. The first segment uses the physics of roller coasters to explain the three laws of motion. Energy is defined as the ability to do work; work involves moving something by using a force at a distance. Potential and kinetic energy are discussed. There are three "Test Connection" segments where the host underscores previous lessons dealing with the three laws of motion, the relationship between space flight and the laws of thermodynamics involving heat; and how to apply information about sound waves in helping students to read charts on the GED exam and beyond. A segment called "The Science of Sound" presents a physics teacher who also sings about such physics themes as the mechanics of sound waves. Also covered are distinctions between electricity and magnetism, as well as current and voltage. The electromagnetic spectrum consists of waves traveling at the speed of light, including visible light. Another feature is the use of electromagnetic waves by MRI technician.
