Examine the natural forces of gravity and friction that are constantly at work on Earth. Then discover the principles and forces that govern moving objects — and how we use them to our advantage. Includes four feature segments.
  • Facts About Forces — Presents the law of universal gravitation and the forces of static and kinetic friction.
  • Laws of Motion — Introduces Sir Isaac Newton's three laws of motion and the principles and forces that govern moving objects.
  • Rotation and Revolution — Examines some of the different ways time can be measured, including sidereal and solar time, along with why Earth has days and nights.
  • How We Fly — Looks at how jet engines, wing design, and special building materials allow airplanes to take to the skies.
