Moving bodies with constant mass : bows and arrows(
Visual
)
2 editions published in 2000 in English and held by 8 WorldCat member libraries worldwide
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 firstorder differential equation is then used to find the minimum height from which a parachutist can jump without injury

Modelling with vectors : angular momentum(
Visual
)
1 edition published in 2000 in English and held by 7 WorldCat member libraries worldwide
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 ailerons and the amount of force required to rotate a toy spaceship. The reasons why a spinning top shows precession are also addressed

)
1 edition published in 2000 in English and held by 7 WorldCat member libraries worldwide
Using Newton's second law and a balloonpowered toy car, this program examines how impulse relates to the change in momentum and how the rate of that change equates to the resultant force. In addition, the exhaust velocity of the jetpropelled car is estimated

Bikes and cars(
Visual
)
1 edition published in 2000 in English and held by 6 WorldCat member libraries worldwide
This program considers the idea that circular motion must imply a force or component of a force toward the center of a circle, as in the Newtonian theory of how the Moon orbits the Earth. The reasons why bicyclists lean during turns, why roads are banked, and why car tires react as they do during a turn are investigated

Moments : doors, heart valves, and flicflacs(
Visual
)
1 edition published in 2000 in English and held by 6 WorldCat member libraries worldwide
After explaining the principle of moments, this program shows how apparently dissimilar physical phenomena are actually mathematically similar through the examples of a synthetic heart valve, a lock gate, and the gymnastic maneuver known as a flicflac, or back handspring. The need to make careful approximations during the modeling process is stressed

Simple harmonic motion 3 : resonance(

)
1 edition published in 2000 in English and held by 6 WorldCat member libraries worldwide
In this program, resonance is examined. The value of mathematical models is demonstrated through the physics of applying a timevarying force to a body that fundamentally exhibits simple harmonic motion. Solution techniques for general linear secondorder differential equations are featured

Modelling forces : sliding and toppling(
Visual
)
1 edition published in 2000 in English and held by 6 WorldCat member libraries worldwide
This program discusses how geometry, gravity, and the coefficient of friction determine whether an object slides or topples. The mathematical models behind these phenomena are presented through examples such as ice hockey and skiing. The relationship between sliding and a body's velocity as an exercise in energy conservation is explored as well

2 editions published between 2000 and 2004 in English and held by 5 WorldCat member libraries worldwide
After defining the basic concepts of vectors, this program uses algebra to determine how the resultant of numerous forces acting on a body can be obtained and then equated to the product of mass and acceleration. Kites are employed to exemplify both equilibrium and nonequilibrium conditions

1 edition published in 2000 in English and held by 5 WorldCat member libraries worldwide
This program investigates how the mathematical model of simple harmonic motion becomes more complex through the introduction of damping. The application of simple modeling techniques to create homogeneous linear secondorder differential equations is illustrated

Takeoff moving bodies with constant mass(
Visual
)
1 edition published in 2000 in English and held by 5 WorldCat member libraries worldwide
This program shows that a single mathematical model can describe the takeoff of a wide variety of aircraft, running the gamut from a singleengine trainer to the Concorde. Because the search for approximations is somewhat complex, graphical notation is employed to reveal the interaction and variation of the forces involved. (26 minutes)

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. Realworld examples are included

Moving bodies with variable mass : rockets and avalanches(
Visual
)
1 edition published in 2000 in English and held by 4 WorldCat member libraries worldwide
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 time a skier has to escape a landslide, plus an experiment with eggs and flour, reinforce the lesson
