A 28.8 g yellow air hockey disc elastically strikes a 26.9 g stationary red air hockey disc. If the velocity of the yellow disc before the collision is 33.6 cm/s in the x direction and after the collision it is 10.7 cm/s at an angle 63.4° S of E, what is the velocity of the red disc after the collision?

By the time students learn about all the equations for mechanical energy, momentum, impulse and impact force, they often start to confuse the equations with one another. This is a straightforward, simple look at all of those equations and when to use them.

This NASA video segment explores how Newton's Laws of Motion apply to the drag force on an airplane. Viewers watch an instructor at NASA's National Test Pilot School and learn that the drag force on an airplane in flight is the result of the horizontal momentum of air molecules colliding with the airplane. Viewers also learn that this drag force can be changed by reshaping the airplane, changing the angle of attack, and placing speed brakes on the wings. A demonstration illustrates how the drag force on an object can be determined, while derivations of the drag equation from Newton's second law show how the force can be calculated. Onscreen formulas and calculations represent the forces mathematically. Run time 12:28.

The precise orbit of any heavenly body -- a planet, asteroid, or comet -- is fixed by the laws of conservation of energy and angular momentum. The eccentricity, which determines the shape of an orbit, is intimately linked to the energy and angular momentum of the heavenly body.

From many on-line sources; - in March of 1770 a fight began that set the stage for later confrontation. Attaucks was held up as the first martyr of the American Revolution along with the others killed. In the early 19th century, as the abolitionist movement gained momentum in Boston, supporters lauded Attucks as a black American who played a heroic role in the history of the United States. Because Attucks had Wampanoag ancestors, his story also holds special significance for many Native Americans.

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.

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.
