mass (physics)

"The Billy Goats Gruff had to outsmart the troll to cross a bridge, but could have avoided him entirely if they had built a raft. This book discusses the science of rafts, including a project to build and test your own raft, and includes an 'In the Real World' feature"--Provided by publisher.

Explores how applied physics relates to the design and construction of roller coasters. Describes the physical dynamics of a roller coaster, explaining the role of potential and kinetic energy, friction, gravity, momentum and acceleration. Also introduces how the inertial effects, known as G forces, give roller coaster riders a thrilling experience.

Explains the concepts of motion and balance, looks at the connection between them, and discusses the related topics of gravity, friction, momentum, and equal and opposite reaction.

Provides answers to questions about gravity, mass and weight, and motion, features facts about gravity-related advances and discoveries, and includes profiles of people who have contributed to gravity knowledge.

An introduction to the science of mass.

Presents information about the scientific law of conservation of mass. Discusses physical and chemical changes to matter, the history of the conservation law, energy, and systems of conservation. Includes a glossary, index, and instructions for an experiment.

"Learn all about mass, and then put your knowledge to use with fun experiments. Measure the mass of some stretchy slime, separate liquids by density, and more. Each experiment has easy-to-read directions paired with step-by-step photographs, while colorful graphics describe the supercool science at work"--Back cover.

Introduces the science concept of balance through the use of simple rebus sentences, a rhyming story, and everyday examples. Includes a glossary.

Provides answers to questions about gravity, mass and weight, and motion, features facts about gravity-related advances and discoveries, and includes profiles of people who have contributed to gravity knowledge.
