  1. Chapter 2 Representing Motion

  2. 2.1- Picturing Motion • I can diagram motion by using motion diagrams, particle models, and coordinate systems

  3. How can you tell something has moved? • What does this mean: Motion is relative.

  4. Motion Diagrams vs. Particle Model • Series of images showing the positions of a moving object at equal time intervals • Simplified version of a motion diagram in which the object in motion is replaced by a series of single points

  5. 1. Draw a motion diagram of a runner • Label the time in each picture • 3. What are the two components used to define motion? • 2. Draw a particle model of a bird flying • 4. Give three examples of straight-line motion.

  6. 2.2- Where and When? • I can determine what measurements are vectors and which are scalars.

  7. Coordinate System- tells you the location of the zero point of the variable you are studying and the direction in which the values of the variable increase

  8. Origin- the point at which both variables have the value zero • Position- the separation between an object and the origin • Distance- how far the object is from the origin

  9. Vectors Scalars • Have both magnitude and direction • Examples: • 10 books to the left • 25 students back • 12 km/h west • Only has magnitude • Examples: • 10 books • 25 students • 12 km/h

  10. A student travels south 20.0 meters and east 14.0 meters. What is the distance from his origin to final location “as the crow flies”? • Use skills learned in Algebra!

  11. Math Practice:

  12. Time Interval- difference between two times • Δt= tf-ti • Final Time minus Initial Time • Displacement- Difference between origin and final location • Δ d= df-di • Final Position minus Initial Position

  13. 2.3- Position Time Graphs • I can find the change in time and displacement and plot it on a position-time graph to determine velocity.

  14. 2.4- How Fast? • I can use equations to solve for average and instantaneous velocity.

  15. Average Velocity • v=Δd/Δt • Average velocity is defined as the change in position, divided by the time during which the change occurred. • Velocity vs Speed

  16. Instantaneous Velocity- the speed and direction of an object at a particular instant

  17. One Sentence Summary • Read pages 46-47 Average Velocity on Motion Diagrams. • Write a one sentence summary as an exit slip for today!
