An example of two people pulling a stalled car is used to show how energy efficiency can be calculated with force vectors. The program also takes a look at how force vectors are considered in the construction of roofs in areas with heavy snowfalls, and illustrates the factors that influence the motion of a mass on an inclined plane.

		Applications of Quadratics Several common applications of quadratic equations are explained through real-world scenarios. Newton's law for describing the path of a projectile is examined, along with some static geometry problems that hinge on quadratics; in addition, a quadra...(more details)		VHS $49.95 DVD $49.95 DVD + 3-Year Streaming $74.93 3-Year Streaming $49.95
		Applications of Sinusoidal Waves Several applications of sinusoidal waves are presented, including the path of a pendulum. A discussion of acoustics leads to a look at how the characteristics of a sinusoidal wave affect the quality of the produced sound, in pitch, intensity, and ton...(more details)		VHS $49.95 DVD $49.95
		Applications of Sine and Cosine Laws Several oblique triangles are solved by means of the sine and cosine laws, and viewers learn how to select and use the law that will work for each triangle. (10 minutes)(more details)		VHS $49.95 DVD $49.95
		Force The concept of force as a vector in the real world is introduced with examples showing how force influences stationary and moving objects. Vectors are also used to calculate the most energy-efficient position for pushing or pulling a heavy load. (10 ...(more details)		VHS $49.95 DVD $49.95
