Teams On the sticky note, respond to the following prompt (in a complete sentence): ▫Describe at least one interesting (and appropriate!) fact about you that Miss Roe, or the rest of the class, might not know about. Once your team is done: ▫Introduce yourselves and share your facts ▫Select team name ▫Select team representative The representative will introduce the team to the whole class 5 min

Materials – Day Two 1 person from team collect notebooks On the cover: ▫Full Name (Print neatly) ▫Class Name and Period (eg. Physics 1) On the first line of the first page: ▫ Today’s date - September 1, 2011 ▫Assignment Title – Observing Like a Physicist 5 min

Observing Like a Physicist Observe the motion of the object on display In your notebook: ▫Draw a small sketch of the system in motion ▫Make a list of words and phrases that you could use to describe this motion  If you are stuck, quietly discuss with your team As a class, create a word bank Use the word bank to write at least one complete sentence describing the motion of the object 20 min

Unit 1.1 Kinematics: 1-Dimensional Motion Physics Miss Roe

Do Now – Lesson 1 Examine this graph ▫What does this graph tell you? ▫What DOESN’T this graph tell you? ▫What other information do you need to know in order to FULLY interpret this graph?

Activity Making Line Graphs

Do Now – Lesson 2 This is a graph of position versus time What is position? How is it measured? What did Miss Roe have to do or how did she have to move in order to generate this graph?

“Free” Spark Time This year we will be using a data collection system called a Spark Today, you will have the chance to learn how to use the Spark to collect data about motion

Do Now – Lesson 3 In your notebook, briefly describe how to: 1.Turn the SPARK on and off 2.Attach a sensor 3.Display a graph, data table, and instantaneous reading 4.Start and stop collecting data 5.Take a snapshot 6.Save your data file

Predict, Test and Sketch Sketch the five position vs time graphs in your notebook For each graph: ▫Predict how you would have to move to generate the same graph ▫Test your prediction using the SPARK p t p t p t p t p t

Do Now – Lesson 4 Write at LEAST one sentence describing the motion represented by this position vs time graph

Position, Direction, Displacement Position Direction Displacement

Do Now – Lesson 5 What is speed? What does this position vs time graph tell you about the speed of the object?

Speed vs Velocity SpeedVelocity

“Free” Spark Time Velocity vs Time graphs ▫Test out different motions ▫Determine how velocity vs time graphs look

Do Now – Lesson 6 Write at LEAST one sentence describing the motion represented by this velocity vs time graph

Predict, Test and Sketch Sketch the five velocity vs time graphs in your notebook For each graph: ▫Make a prediction about the motion being represented ▫Test your prediction using the SPARK data collection tool v t v t v t v t v t

Do Now – Lesson 7 What does the slope of a position vs time graph represent? (Look back in your notes!) How do you calculate the slope of a line?

Deriving Formulas: Average Velocity

Do Now – Lesson 8 Cars and other vehicles have features that allow you to change the velocity. What are they called? A commercial states that a car “can go from zero to 60 in 1.38 seconds” … what does that mean?

Acceleration The rate at which velocity changes What would a formula for acceleration look like?

Problem Solving Workshop On a post-it, identify: ▫which problems you need help with OR ▫which problem solving step(s) you are struggling with:  Identifying givens/unknown  Selecting the correct equation  Rearranging the equation  Calculating numbers  Simplifying units  Converting units ▫Anything else??

Do Now – Lesson 10 Think about the changes in motion a ball will undergo as it is tossed straight up and down. 1.Make a sketch of your prediction for the position vs. time graph. Describe in words what this graph means. 2.Make a sketch of your prediction for the velocity vs. time graph. Describe in words what this graph means. 3.Make a sketch of your prediction for the acceleration vs. time graph. Describe in words what this graph means.

Lab - Ball Toss Switch motion sensor to the cart setting Build three lab pages: ▫Position vs time, Velocity vs time, Acceleration vs time The motion sensor must be on a flat surface, grill facing directly up Try to avoid keeping your hands in front of the sensor but DO NOT let the ball hit the sensor! NO PLAYING around the SPARKS and sensor!!

Lab – Analyzing Data To select a portion of the graph: ▫Quickly tap twice on the graph. ▫An area of the graph will be highlighted, with red “handles” you can tap and drag to extend the selection area Graph Tools: ▫Text function (T) for labels ▫Line Fit function for equation of a line ▫Statistics button (Σ) for mean, max, min, etc.

Do Now – Lesson 11 List all the formulas we have used so far in this class How do you calculate an average?

Deriving Displacement Part 1: How far did it fall?

Deriving Final Velocity Part 1: How fast will it go?

Deriving Displacement: How far did it fall? Part 2

Deriving Final Velocity – How fast will it go? Part 2

What about free fall? These four final equations can only be used when the acceleration is constant. Gravity causes a constant acceleration for any falling object (or one that has been thrown straight up into the air). If using these equations for an object in free fall, substitute the acceleration, a, with the acceleration due to gravity, g
