TAILIEUCHUNG - Ebook Physical science: Forces and Motion

(bq) Ebook Physical science: Forces and Motion helps you know How do balanced forces affect the motion of an object? Explain how the Moon’s gravitational pull can be observed on Earth; How is instantaneous speed different from average speed? It is necessary to have a frame of reference to describe motion. | Genre Comprehension Skill Text Features Science Content Nonfiction Predict Captions Charts Diagrams Glossary Forces and Motion Scott Foresman Science PEARSON Scott Foresman ISBN 0-328-14012-0 IB. -I Vocabulary acceleration force friction gravitational force inertia momentum speed velocity Illustrations Title Page 4 5 11 13 15 16 clint Hansen 1 6 Peter Bollinger Photographs Every effort has been made to secure permission and provide appropriate credit for photographic materiai.
