1. DSQ
If you remember your childhood, the hare challenges a tortoise to a race, lets say it was 5 miles. Use the graph to answer the following questions.
1.) Who’s speed is faster during the first 5 min.
2.) What did the hare do 5-20 min?
3.) Who won the race?
4.) Who has the higher average speed?

2. DSQ

5. Update Notebook
We are going to rip out the miscellaneous section and replace it with a vocabulary section. When finished, please write down these vocab words.
1. Physics - “the study of matter, energy, and the interaction between them”
2. Motion – distance from another object is changing
3. Speed = D/T
4. Velocity = Speed + Direction

6. Motion
An object is in motion when it’s distance is changing from another object.
Reference Point – a point, place, or object that is used for comparison to determine if something is in motion.
Relative motion – relative to what Mr. Officer.

7. International System of Units (SI) System
Based on the number ten.
3 awesome things about it
Easy to convert
The rest of the word uses it
Can measure small things
Bad news;
You didn’t grow up with it so you have to play catch up and get use to it because it’s what we use in science

8. Speed
Speed = Distance / Time

9. Speed Speed = Distance / Time
If Steve throws the football 60 meters in 3 seconds, what is the average speed of the football?
A baseball is thrown a distance of 20 meters. What is its speed if it takes 0.5 seconds to cover the distance?

10. Velocity Velocity = Speed + Direction
A truck moves 100 miles to the south in 2 hours. What is the trucks velocity?
A regulation NBA basketball court is 94 feet long. If Wale runs the length of the court (from left to right) in 5 seconds, what is his velocity?

11. Graphing Motion
Traditionally time is shown on the x-axis and distance on the y-axis.
Side note- independent variable = x-axis, Dependent variable = y-axis.
A straight line represents constant speed
The slope of the line represents the how quickly or slowly the object is moving
