1. How can an objects motion be described?

2.  Homework: Finish, “What I Learned,” List Started in class in notebook. Read pgs. 7-11 in textbook  Do Now: Write down homework, Open textbook to pg. 6  Update TOC: pg. 20- Chapter 1-Motion Title page Pg. 21- Describing Motion

3.  What I know:  An object is moving when it changes position  Objects move at different speeds  This effects how long it takes for an object to travel a certain distance..

4.  The one who walked faster got there quicker, traveling the same distance in less time.

5.  Motion- An object is in motion if its distance from another object is changing.  Reference point- is a place or object used for comparison to determine is something is in motion.  An object is in motion if it changes position relative to a reference point.

6.  Are students on a bus moving compared to a person standing on the side walk? Why? ◦ Yes, because the distance between the students and the person on the sidewalk is changing  Are the students seated on the bus moving compared to the bus? Why? ◦ No, because the distance between the bus and the students does not change.

7.  Objects that are stationary, (not moving).  Examples:

8.  If you choose a moving reference point, ◦ You may think that you are moving when you are not ◦ Or that you are moving faster or slower than you really are. Read over pg. 7 to pg. 8

9.  Something I learned about motion  Another thing I learned about motion  One more thing I learned about motion

10.  Homework: Speed worksheet.  Do Now: Write down homework,  Update TOC : pg. 22- Calculating speed  Open textbook to pages 10 & 11:  Then Define: all highlighted terms and write the speed equation, on pg. 22  Today I will Calculate an objects speed

11.  To measure distance the SI unit used is for length is meter (m).  Motion is compared to a reference point

12.  The distance an object travels per unit of time.  If you know the distance an object travels in a certain amount of time you can calculate the speed

13.  Speed = Distance/ Time What is the Speed of a asteroid traveling 4500km in 6 seconds?  What are two ways to increase this speed? ◦ Increase the distance ◦ Decrease the time

14.  Average Speed: The total distance divided by the total time  Instantaneous Speed: The rate that an object is moving at a given instant of time.
