| 1191286682 | v₁₂ = | v₁ − v₂ | |
| 1191286683 | v₁ = | v₁ 's actual velocity | |
| 1191286684 | v₂ = | v₂ 's actual velocity | |
| 1191286685 | v₁₂ = (in words) | The velocity of 1 with respect to 2. What 1 looks like from 2. | |
| 1191286686 | Shortest Distance = | 1. Find Relative Velocity. 2. Draw a diagram. 3. Find angle of relative velocity vecter 4. Use sin to find the ⊥ distance. | |
| 1191286687 | Two Cars at Junction = | Move one car to junction and find the others position at the time. Continue | |
| 1191286688 | Two straight Road intersect at an angle θ = | Move one car to junction and find the others position at the time. Continue | |
| 1191286689 | Velocity of the boat in Still Water = | Velocity of the boat with respect to the river. | |
| 1191286690 | Quickest Route (river) = | Time is a minimum, velocity of the boat with respect to the river is directly across. | |
| 1191286691 | Shortest Route (river) = | Velocity of the current is opposite the "i" component of the relative velocity of the boat. | |
| 1191286692 | Apparent Velocity of wind = | Velocity of the wind w.r.t. the person. | |
| 1191286693 | Apparent Velocity Problems = | Let velocity of the person = x i + y j. End up with simultaneous equations. | |
| 1191286694 | Apparent Velocity, NE = | i component = j component | |
| 1191286695 | Apparent Velocity, NW = | i component = − j component | |
| 1191286696 | Apparent Velocity, N = | i component = 0, j component >1 | |
| 1191286697 | Apparent Velocity, W = | j component = 0 , i component <1 | |
| 1191286698 | Apparent Velocity, SE = | i component = − j component | |
