Slicing the Cone
 The standard double right circular cone is introduced, and the seven conic sections are discovered when the cone is sliced at various positions and angles with a plane. The circle, ellipse, parabola, and hyperbola are explored in detail, and their fu...(more details) |

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) |

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) |

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) |

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) |
