Energy and Work

Dorthy Montgomery uses a Leybold tube to measure the curvature of the path of the electrons in a magnetic field and thus determine the mass of the elctron. Director, Jack Churchill, Explains the various ways that the different forms of energy change; illustrates and describes the forms of energy, and shows how they may be put to work. Pictures through time-lapse motion picture techniques a boy "full of energy" mowing the lawn after which he also can store some of his energy in the windings of a rubber band within his airplane. Cites the gasoline in a power mower and a circus sandbag lifted up into the air as other examples of potential energy. Depicts kinetic energy in moving objects such as a bowling ball, a wrecking ball, and a moving water wheel. Views the conversion of water power to electric power through the use of water wheels and a generator.

Dorthy Montgomery uses a Leybold tube to measure the curvature of the path of the electrons in a magnetic field and thus determine the mass of the elctron. Director, Jack Churchill, How work, measured as the area under the force-distance curve, measures the transfer of kinetic energy to a body, calculated from its mass and speed. Work demonstrated as a useful measure of energy in various situations., NOTE: Two (or more) records have been merged together to create this data.
