2.  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.  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.  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.  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!

13.  Time Interval- difference between two times › Δt= t f -t i › Final Time minus Initial Time  Displacement- Difference between origin and final location › Δ d= d f -d i › Final Position minus Initial Position

14.  I can find the change in time and displacement and plot it on a position- time graph to determine velocity.

19.  I can use equations to solve for average and instantaneous velocity.

20.  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

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

22.  Read pages 46-47 Average Velocity on Motion Diagrams.  Write a one sentence summary as an exit slip for today!
