Motion is a change in an object's position. This fascinating title explains in a clear, simple way how objects are moved by a change in energy. Simple activities show young readers how energy is changed by applying a force, either by coming in contact with an object or by a force that does not touch it physically, like gravity. Teacher's guide available.

Learn how things get moving and what makes them stop.

Explains the physics of gravity and gravitational pull, offering information on the contributions made in this area by Copernicus, Galileo, and Newton.

Idealistic characters fight to hold onto a life that is slipping out of their grasp. Newton's Laws of Motion describe how bodies work to balance forces outside their control. For the men and women in States of Motion, imbalance is a way of life. Set in Michigan small towns both real and fictional, the stories in Laura Hulthen Thomas’s collection take place against a backdrop of economic turmoil and the domestic cost of the war on terror. As familiar places, privilege, and faith disappear, what remains leaves these broken characters wondering what hope is left for them. These stories follow blue collars and white, cops and immigrants, and mothers and sons as they defend a world that is quickly vanishing. The eight stories in States of Motion follow tough, quixotic characters struggling to reinvent themselves even as they cling to what they’ve lost. A grieving father embraces his town’s suspicions of him as the sole suspect in his daughter’s disappearance. A driving instructor struggles to care for his abusive mother between training lessons with two flirtatious teens. A behavioral researcher studying the fear response must face her own fears when her childhood attacker returns to ask for her forgiveness. Conditioned by their traumatic pasts to be both sympathetic and numb to suffering, the characters in these stories clutch at a chance to find peace on the other side of terror. From the isolated roadways of Michigan’s countryside to the research labs of a major university, the way forward is both one last hope and a deep-seated fear. The profoundly emotional stories in States of Motion will interest any reader of contemporary literary fiction.

"A graphic nonfiction volume that introduces the properties of force and motion. Features include several photographic pages, a glossary, additional resource list, and an index"--

Jason Zimba offers a new visual presentation of Newton's three laws of motion, allowing students a new perspective on the conceptual underpinnings of laws that fundamentally explain the workings of the universe.

This debut collection explores memory, cities, motion. Tung-Hui Hu's tone has some of the swampy wit that recalls Calvino or Michaux: A man swaps bodies with his lover; a mapmaker holds captive a city, which needs his crystal telescope to navigate through streets "unreadable as palm lines"; a car pushed off a cliff in a fit of anger becomes home for a school of fish. Anchored by the sequence "Elegies for self," Hu's poetry brings a quiet sophistication to syntax, diction, and form.
