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 minutes)

		Follow That Arrow Characteristics of vectors and the rules that govern their behavior are introduced, and the concepts of magnitude and direction are developed with computer animation. A futuristic police chase shows how vectors are used for predicting the direction o...(more details)		VHS $49.95 DVD $49.95
		Applying Forces 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, a...(more details)		VHS $49.95 DVD $49.95
		Finding the Resultant Two vectors that have the same magnitude and direction are equal. Computer animation is used to show that two vectors can be joined by sliding one to the other, and by means of this action, the resultant of both vectors can be found. (10 minutes)(more details)		VHS $49.95 DVD $49.95
		Ordered Pairs When the components of a vector are found, their magnitudes can be used to describe the vector. With the horizontal value first, and the vertical value second, the vector is defined by an ordered pair. A ship's course is used to demonstrate the way i...(more details)		VHS $49.95 DVD $49.95
		Resolving Without Grids The resultant of multiple vectors can be found more easily and quickly by adding ordered pairs than by drawing all the vectors and performing calculations. Examples of vectors in space are developed, and the program shows how a vector can be resolved...(more details)		VHS $49.95 DVD $49.95
