This NASA video segment explores how Newton's Laws of Motion apply to the lift of an airplane. An instructor at NASA's National Test Pilot School teaches that for an airplane to overcome the downward force of its weight, it must change the momentum of the air molecules colliding with the wings. This is accomplished by changing the air's vertical velocity through increased propeller speed, sharpened angles of attack, widened wings or curved wings. Onscreen formulas and calculations represent the forces mathematically. For example, in one part, the instructor derives a formula from Newton's second law to calculate the minimum flying speed of an aircraft. The instructor then flies the aircraft to test his calculations. Run time 14:15.

This three-minute video explains how a slave ship captain, such as Luke Collingswood, had the power to do whatever was necessary to maintain control, while bringing ships of slaves across the ocean for trade. This video shows how the British people finally found out what the slave ships was like and those that testified against it, including a clergyman who was once a slave captain and later wrote Amazing Grace, John Newton.

Kitchens are full of fluids you might never have known were there. A fluid can be a liquid, gas, solid, or even plasma. Viscosity Sir Isaac Newton and his three laws of motion are also explained as related to foods. (03:47)

Join award winning teacher Jonathan Bergmann as he interactively teaches Astronomy: Solving the Problem of Astronomical Motion. Astronomers of antiquity did not connect gravity and astronomical motion. Galileo investigated this connection with experiments using projectiles and balls rolling down planks. Galileo put science on course to determine laws of motion and to develop the scientific method. After this introduction, the concept of gravity is explained and demonstrated. Newton's theories on the motion of the moon are also explained. (09:14)

Lesson Objective: Create a key experience for a unit on Newton’s Laws. Questions to Consider: See how a physics demonstration shows kids why they need to wear a helmet. How does Mr. Rettberg use the demonstration as a touchstone experience? How does Mr. Rettberg reinforce difficult concepts and vocabulary? (07:29)

This NASA video segment explores how Newton's second law applies to the thrust force on an airplane. Viewers watch an instructor at NASA's National Test Pilot School and learn that an airplane's engines work to change the horizontal momentum of the air surrounding the airplane. Viewers also learn that this change in momentum is accomplished through increased propeller speed, increased propeller diameter or increased air pressure in the jet engines. Onscreen formulas and calculations represent the forces mathematically. For example, in one part, the instructor uses Newton's second law to derive an equation to find the minimum rpm's needed to provide enough thrust to an airplane.

This NASA video segment explores how Newton's laws apply to the takeoff of an airplane. Viewers watch an instructor and engineer at NASA's National Test Pilot School and learn that there are four opposing forces on an airplane, that takeoff is the point at which the lift just starts to offset the weight, and that the distance needed for takeoff can be calculated using an equation derived from Newton's second law. The video clip also discusses the extra drag force created by the rolling friction of the airplane's wheels.

This NASA video segment explores how Newton's laws apply to the landing of an airplane. Viewers watch an instructor at NASA's National Test Pilot School and learn that the approach is the first phase of landing an airplane, that the flaps on an airplane's wings help decrease the speed of the aircraft, and that the curvature of the wings helps keep the airplane aloft at slower speeds.

This NASA video segment explores how Newton's laws apply to landing an airplane. Viewers watch an instructor at NASA's National Test Pilot School and learn that landing an airplane involves three phases, that the airplane's mass and touchdown velocity determine the necessary runway length, and that smooth landings require pilot skill in balancing forces. The instructor explains how to calculate the minimal runway length. (13:45)

This NASA video segment explores how Newton's laws can be used to assess an airplane's cruise performance. By watching an instructor at NASA's National Test Pilot School, viewers learn how an aircraft's cruise performance is evaluated and how this performance can be maximized. Viewers also learn how to rearrange the lift and drag equations to find the ratio of the coefficient of lift to the coefficient of drag that will provide maximum performance. Using a graph of these coefficients, the instructor demonstrates how to solve for the maximum endurance speed of the plane and then tests the calculation in an airplane.

Wearing a helmet is all about impulse, change in momentum and the force of impact. This video illustrates why you should secure your helmet to your head. Thank you very much to Colton and Jean Johnson who said yes when I asked them if I could film myself riding my bike off their dock. Colton also said, “In my 75 years of living, that has got to be the strangest request I have ever received.” Thank you also to Chris Palmer and Larry Braak for being my on-site camera operators.

Early Greek astronomers believed that Earth was the center of the universe. However, this notion changed dramatically over time, especially after the invention of the telescope. This program traces the development of astronomical theory with discussions of the discoveries of Copernicus, Galileo, Kepler, and Newton. Unique characteristics of Earth are also discussed.
