  1. Motion & Its Applications: Vectors & Scalars

  2. Vectors vs. Scalars • Scalars: Any quantity that has only magnitude. • i.e: 30 sec., 59kg and 10m • Vector: Any quantity that has both magnitude AND direction. • i.e: 30m [Up], 5m/s [W] and 200N [Down]

  3. Comparing traditional measured quantities: • Note: All vectors must be represented using harpoon notation. i.e

  4. Average Speed & Velocity • Average Speed: The distance an object travels over a certain time interval. • Average Velocity: The displacement an object travels over a certain time interval. (Distance) (Time) (Displacement) (Time)

  5. Eg.3: Calculate the average speed in each of the following, express answer in SI. • A jogger takes 14s to run 88m. • A truck travels 425 km in 4.65h • Eg.4: A jogger takes 3.5 min to run once around a square city block that is 220m on each side. Express in SI. • What was the jogger’s average speed? • What was the jogger’s average velocity?
