NOTE TO TEACHERS: 
These procedures are written to show you how you might use these technologies to teach science concepts. Suggested questions, approaches, and expected answers are all provided. Therefore, these activity descriptions should be used as a guide for your instructional planning, rather than as step-by-step directions for students.

Getting Started

Three tugboats are pulling a cruise ship in different directions. In which direction will the cruise ship move?

Let's say, specifically, the three forces applied by the tugboats are 100 Newtons (N) at 39°, 150N at 167° and 140N at 250°.

To figure out in which direction the cruise ship will move, you could (1) go see a trigonometry teacher or (2) open the vector simulation.
