Motion Homework
We will have the Mastery Quiz tomorrow
Did you have any questions on the law of conservation of mass

3. Homework
I will check the homework when we are solving speed and velocity problems
Whatever we don’t finish in class will be homework tonight

4. London 400m Womens Final
What are some examples of motion in the video?
How do you describe the motion?
How would you measure motion?

5. Objectives Given notes and homework, SWBAT define speed and velocity.
Given real-world examples, SWBAT determine examples as speed or velocity.
Essential Questions
How do you calculate speed and velocity and what units do you use? What are the similarities and differences between speed and velocity? What are some directions used for velocity?

6. Definition of speed and velocity
In the textbook and what you should have for questions 1 and 2 in the motion HW
Speed
The distance traveled divided by the time interval during which the motion occurred
Velocity
Quantity describing both speed and direction
With your tables, come up with your own definitions of speed and velocity and write it on your paper.
You have 3 minutes

7. How are speed and velocity different?
Velocity needs to include a direction

8. How do we find speed and velocity
Distance/time
It takes Mr. Littman 30 minutes to drive to school and he drives 11 miles from his house. What is Mr. Littman’s speed

9. How do we find speed and velocity
Distance/time
It takes Mr. Littman 30 minutes to drive to school and he drives 11 miles from his house. What is Mr. Littman’s speed
11 miles/ 30 minutes
22 miles/hour
In order to make it velocity, you add a direction
22 miles/hour South

10. Sometimes you might need to find the time or distance
Lets solve together
If I travel at 20 km/hr for 15 minutes, how far will I travel?
If I travel at 40 m/s how long will it take me to travel 200 meters?

11. Answer the Essential Question
How do you calculate speed and velocity and what units do you use? What are the similarities and differences between speed and velocity? What are some directions used for velocity?

12. Exit Ticket In 1 complete sentence, define speed.
In 1 complete sentence, define velocity.
In 1 precise, scientific sentence, describe how speed and velocity differ.
A car leaving Nashville is headed to Bowling Green, KY. The car is traveling at 80 km/hr up highway 65 North. How far will the car be from Nashville in 1.5 hours? Is this giving you speed or velocity?
