Defines field as an area in which a force can be felt. Shows how the earth's gravitational field affects objects on the earth. Topics: Basic-Physical-Science-Earth; Basic-Physical-Science-Electricity-And-Magnetism, Uses animated drawings with live-action scenes to define the characteristics of fields and to illustrate their practical applications. Shows the gravitational field on the moon's orbit, and of electric fields on materials such as wood, glass,and steel. Collaborator, Albert V. Baez., Through demonstrations and drawings, shows characteristics of magnetic, electric and gravitational fields. Defines field as an area in which a force can be felt. Shows how the earth's gravitational field affects objects on the earth.NOTE: Two (or more) records have been merged together to create this data.
