| Question | Answer |
|---|---|
| Arrows represent | two-dimensional vectors |
| The length of the arrow represents | the magnitude |
| Magnitude | tells “how much” |
| Rule 3.1 (Arrows) | Arrows represent two-dimensional vectors. The length of the arrow is the magnitude of the vector while the arrow points out the direction. |
| Rule 3.2 (adding vectors) | When adding vectors graphically, take the tail of the second vector and place it at the head of the first vector. The vector that then completes the triangle by starting at the tail of the first and pointing to the head of the second represents the sum of the two vectors. |
| Two-dimensional motion | motion that occurs in a plane |
