power (mechanics)

Discovers what forces are, how they are measured, and how we use them to kick a ball and slide down a water slide through simple experiments.

An encyclopedia of science and technology that examines energy sources, and describes the generation and use of electricity, and surveys power-producing machines.

This book traces the progress of technology used to create energy to run machines from ancient watermills and windmills to today's biofuels, solar cells, and other renewable resources.

Introduces energy and provides instructions for an activity to demonstrate some of its characters.

Discusses nuclear, plant, water, wind, solar, and earth power, how they are stored and used, and why they must be conserved.

Introduces readers to the many different types of energy used in everyday technology, including light, sound, heat, and electrical energies.

Presents scientific experiments that explore energy and its properties as well as the increasing problems of depletion of natural energy resources.

Surveys the uses of energy sources as they have evolved from earliest days and emphasizes resultant pollution problems and the present energy crisis.

Describes the sources and uses of various kinds of energy and the need for energy conservation.

Instructions for a variety of projects and experiments demonstrating basic concepts of energy, work, and power, including thermal, electrical, and solar energy, energy of motion and position, and energy conservation.
