power (mechanics)

The simplest machines are the lever, wheel and axle, pulley, ramp, and screw. The electric motor was first invented in 1832, and was used commercially for the first time 41 years later. Examine significant developments in the generation and use of power in Power and Energy, one of the titles in the Technology and Innovation series.

An introduction to kinetic energy describing the basics of mechanical energy.

"Do you want to make the best paper airplane? Or perhaps centripetal force and the idea that water can defy gravity excites you! This is the book for curious young physicists, ready to learn more about the world around them. Each of the 10 projects includes a Background section to explain the science topic at work, materials, clear step-by-step instructions, and an Observations section walking readers through the results they likely saw. Several projects include science fair ideas and expanded versions of the experiment to engage readers further. A discussion of the scientific method and helpful glossary conclude the book"--.

Physical science can be a challenging topic for readers at any level, but this creative guide to physics breaks down essential concepts in a creative and accessible way. Text relating to forces and matter is presented in very short snippets, including bullet points, highlighted fun facts and statistics, and descriptions on diagrams. This is designed to help readers see that learning about science is anything but boring! Images play a large role in this learning experience, with information being presented in the form of graphic organizers, infographics, and a combination of illustrations and photographs.

Uses simple explanations and color photographs to teach children how different forces work, including gravity and friction.

Readers learn what mechanical energy is and how it has been harnessed in inventive ways over the course of history.

Discusses machines over the centuries from the wheel to horseless carriages to hovercraft and robots.

Discusses the issues surrounding implementation of a smart grid, including security concerns, the impact on energy production and distribution, and the social acceptance of a smart grid.

Discusses what mechanical energy is and how it can be created.
