Using visual examples and basic calculations, this program defines and illustrates the concept of force, with an emphasis on the relationship between force and motion. Several kinds of forces are examined, including gravity, friction, and centripetal, centrifugal, magnetic, electromagnetic, electrostatic, and nuclear forces. The experiments and findings of Galileo and Newton are introduced as well.

This Science Screen Report explains the forces that come into play when a cyclist puts on the breaks, a pitcher throws a curve, and an airplane takes to the sky. Focusing on such concepts as acceleration, terminal velocity, friction, and balanced and unbalanced forces, the program also delineates Newton's laws of motion and Bernoulli's principle of pressurized air and fluid behavior. For discussions in applied or theoretical science, this is a skillful...

Ever since there has been work to do, people have looked for easier ways to complete their tasks. These imaginative videos offer fresh perspectives on how machines are used to make work easier. Animation, graphics, video, and narration are combined to vividly explain the basic physical concepts associated with work, energy, and the six simple machines. Special appearances by a hard-working caveman help put the development of machines into historical...

Section one of this program sheds light on the behavior of springs and pendulums undergoing simple harmonic motion, illuminating the application of Hooke's Law and the formula for calculating oscillation. In section two, physics experts like "Working Joe" discuss wave terminology, principles such as periodic waves, and wave types, including transverse, longitudinal, and surface waves. Examples using rope, a radio, and an electric guitar reinforce...

When you use baseball to demonstrate the principles of physics, your students will see science in a whole new way. Divided into four segments, this program takes a close look at the pitch (how gravity, drag, and the Magnus force are used to manipulate the path of the ball); the hit (kinetic energy, the coefficient of restitution, and Newton's Laws of Motion-and the changes that result when rawhide meets wood); the flight (the effects of launch angle,...

This program travels to the home of Colossus-the world's first ten-inversion steel roller coaster-to reveal the physical, mechanical, and psychological forces that make the roller coaster the undisputed king of thrill rides. Concepting, computer-assisted track design, 3-D simulation, track construction, and car safety mechanisms are covered by some of the experts who know roller coasters best. The goal? Pulse-pounding speed and mind-blowing disorientation...

This program introduces the "plane facts" of two-dimensional kinematics via Bright-As-Light, the two-dimensional super girl. Using scenarios based on soccer and archery, the projectile motion equations for calculating initial horizontal and vertical magnitudes, horizontal and vertical velocities, and horizontal and vertical displacements are analyzed in detail.

Want to know where to sit on a roller coaster to get the biggest thrill? In this program, engineers use the principles of physics to design amusement park rides. Viewers will be catapulted along on a roller coaster, slammed into their seats, glued against a wall, shot down a luge course, and swung around on a hellacious ride they call "the corkscrew. As they go, they learn the relationship between kinetic and potential energy, vectors, speed, friction,...

Can a giant hunk of chocolate be used to illustrate friction? It is in section one of this program, which describes kinetic and static friction, the normal force, and the coefficient of friction. In section two, a group of construction workers and the cartoon brothers Bumpkin Bill and Urban Tom elucidate the true nature of work, power, and energy. The Work-Kinetic Energy Principle is also addressed in an example using the "Alexandria Ferro XL" sports...

In order to be a competent pilot, one must develop a thorough understanding of how and why a plane flies, as well as the forces that affect the flight of an aircraft. This video gives viewers just that. It outlines the forces of Lift and Gravity on an aircraft and goes on to describe how different structures on the plane are used to control these forces. Experts on aeronautics and flight give exciting commentary on their area of expertise.
