Moving beyond the concept of simple force, this program expands the application of vectors to include velocity, acceleration, and rotational motion. In addition, moments of greater complexity are investigated through vector geometry. Real-world examples are included. (56 minutes)

Modeling Vectors
View Video Clip
Employing diverse examples such as trains and water slides, this program illustrates the use of vectors to represent forces operating in both two and three dimensions. The algebraic manipulation of vectors in modeling problems is featured. (24 minute...(more details)
 
Parachuting: Moving Bodies with Constant Mass
View Video Clip
This program uses a parachutist to demonstrate the effects of drag on the force of gravity, showing how to make mathematical approximations and how the resultant forces can be equated to the product of mass and acceleration. A first-order differentia...(more details)
 
Rockets and Avalanches: Moving Bodies with Variable Mass
View Video Clip
In this program, footage of rockets blasting off and avalanches roaring down mountainsides provides two perspectives of the same principle: the rate of change of momentum. Practical calculations of the time it takes for a rocket to lift off and the t...(more details)
 
Spinning Tops and Ailerons: Moments and Angular Momentum
View Video Clip
In this program, animated graphics help to define the concept of angular momentum and to express the relationship between moments and the rate of change of angular momentum. Problems include determining the dimensions needed for an airplane's aileron...(more details)
 
Resonance: Simple Harmonic Motion
View Video Clip
In this program, resonance is examined. The value of mathematical models is demonstrated through the physics of applying a time-varying force to a body that fundamentally exhibits simple harmonic motion. Solution techniques for general linear second-...(more details)
