gravity

This book traces our knowledge of gravity over time and in different cultures through biographical accounts and describes experiments and conclusions drawn from experiments.

Einstein introduces the concepts of light and gravity to young readers.

Explains how acrobats use balance and motion, describes how gravity affects the stability and instability of objects, and features illustrated, step-by-step instructions for related experiments and craft projects.

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.

When Mott wakes up confused and irritable one morning, he finds himself in one upside down adventure after another, until he doesn't know what's up and what's down.

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 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.

Galileo, having observed a young boy dropping food from a bridge into his uncle's boat, conducts several experiments to study gravity.
