gravity

By the age of 23, he had laid the foundations for calculus, the laws of gravity, motion and inertia, and begun experiments on light. His major work is called 'The Principia'. Isaac Newton has been called the Father of Modern Science. His incredible body of work represents arguably the greatest contribution to science ever made by an individual. But despite living at the vibrant center of an inspired social scene, his personal life was marked by loneliness. Examine the many discoveries and private fears of this remarkable man.

An overview of forces and gravity, covering how these things shape and control everything in the universe as well as topics such as friction and magnetism.

Examines the contributions of early scientists in the field of physics, discussing Galileo's observations of falling objects, Sir Isaac Newton's laws of motion and gravity, and Albert Einstein's theory of relativity and the idea of a space-time continuum; and looks at the loss of the space shuttle "Columbia" and its crew, and the physics of space shuttle design.

Examines the natural forces of gravity and friction that are constantly at work on Earth. Demonstrates the principles and forces that govern moving objects and how we use them to our advantage. Part 1 presents the law of universal gravitation and the forces of static and kinetic friction. Part 2 introduces Sir Isaac Newton's three laws of motion and the principles and forces that govern moving objects. Part 3 examines some of the different ways time can be measured, including sidereal and solar time. This section also examines why Earth has days and nights. Part 4 investigates jet engines, wing design, and special building materials that allow airplanes to take to the skies.

Simple experiments demonstrate the laws of gravity.

Contents include : atmosphere, bubbles, compass, electricity, evaporation, friction, frostbite, gravity, lightbulbs, lodestones, Isaac Newton, Pythagoras, rainbows, roller-coasters, smoke signals, snowflakes, sundials, water pressure, etc.

An introduction to gravity, explaining what it is and how it works on Earth and in outer space. Includes an activity, fun facts, and a glossary.

Defines gravity, one of the four forces that control the universe and the most mysterious, and discusses Newton's theory about the force of gravity which still didn't explain how gravity works at a distance. Einstein understood that gravity and acceleration are interchangeable and thus devised his theory of general relativity which explains how gravity works. Includes chapter notes and an index.

With the help of an adventurous scientist and his fun-loving dog, kids learn about the mysterious force of gravity.

An introduction to gravity that defines what it is, discusses the study of it, describes what the effects of more or less gravity on Earth would be, and includes a related activity.
