Cliff Notes I. Vectors A. Velocity is represented by a vector, which looks like an arrow coming out of the object B. Vectors tell us two things: direction and magnitude C. Examples: person --> car ------> cheetah -----------> bullet ---------------> *see "Worksheet on Vectors" below for additional explanations II. Velocity A. Change in position over time B. Velocity has two components: speed and direction C. How are speed and velocity related? See below  D. Δ position = final position - initial position so...v = Δ position = final position - initial position = Δd time time t Attachments Worksheet on Vectors - additional information on vectors and how they work Displacement and Velocity Worksheet - practice problems with velocity Speed and Velocity Worksheet - additional practice with velocity. Only #7 and 8 are used as examples in class, the other problems are somewhat confusing |
