Using Newton’s second law and a balloon-powered 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 jet-propelled car is estimated. (39 minutes)

		Modeling Vectors 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)		DVD $79.95 DVD + 3-Year Streaming $119.93 3-Year Streaming $79.95
		Bikes and Cars: Centripetal Acceleration 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 ba...(more details)		DVD $79.95 DVD + 3-Year Streaming $119.93 3-Year Streaming $79.95
		Parachuting: Moving Bodies with Constant Mass 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)		DVD $79.95 DVD + 3-Year Streaming $119.93 3-Year Streaming $79.95
		Kites: Modeling with Vectors 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 ...(more details)		DVD $79.95 DVD + 3-Year Streaming $119.93 3-Year Streaming $79.95
		Sliding and Toppling: Modeling Forces 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...(more details)		DVD $79.95 DVD + 3-Year Streaming $119.93 3-Year Streaming $79.95
