DO NOW V: 0 Sketch the following graph on your DO NOW handout. Mon/Tues 11-16-15 to 11-17-15 Sketch the following graph on your DO NOW handout. Compare the objects motion between points A and B and points B and C. B C A

ESSENTIAL QUESTIONS: OBJECTIVE: How do we calculate and communicate the change in position, direction, and speed for moving objects? OBJECTIVE: Students will construct graphs showing changes in distance over time.

Agenda Motion Detector Lab Exit Ticket Today’s Agenda Homework Speed, Velocity, Acceleration, Forces HW QUIZ ON WED/THURS over SPEED, VELOCITY, ACCELERATION, & GRAPHING SPEED. 2nd 6 week Reflection was due last Thursday. You have 1 week to turn in late work. Thursday is the last day I will accept it.

Motion Detector Lab V: 0 Goal: Make the graph that is on your paper, appear on the screen. For Graph 1 Calculator Motion Detector Recorder Walker **If there are only 3 in your group, the walker will also be the recorder.

Exit Ticket V: 0 On your post-it note: What should be included on a graph showing average speed? Name On a graph showing average speed and should be included.

DO NOW V: 0 1. Quickly sketch the graph below. Wed/Thurs 11/18 to 11/19 The graph below shows an object’s speed. (Distance vs Time) 1. Quickly sketch the graph below. 2. What is happening to the walker’s motion between points A and B? 3. Between which 2 points did the walker return to the starting point?

ESSENTIAL QUESTION: DAILY OBJECTIVE: How do we calculate and communicate the change in position, direction, and speed for moving objects? DAILY OBJECTIVE: Students will construct graphs showing changes in speed over time.

AGENDA V: 0 Homework Speed, Velocity, Acceleration, and Forces HW Today’s Agenda Quiz Review Speed, Velocity, Acceleration, and Graphing Quiz Graphing Acceleration: Terminator 2 Chase

Forces, Speed, Velocity, Acceleration Quiz Voice Level 0 Read quietly or work on missed work when finished. We will trade and grade when everyone is finished.

Graphing Acceleration: Terminator 2 Bike Evasion Objective: To gather data, present data in a graph, and analyze the journey of John Connor’s bike ride in Terminator 2. Copy title and objective into page 75 of your INB. Read the directions and glue in the table, be ready to record the times.

Terminator 2 Bike Evasion Objective: To gather data, present data in a graph, and analyze the journey of John Connor’s bike ride in Terminator 2. Procedure: Start your stop watch the moment the boy’s bike starts up. Record the time on the stopwatch when the boy reaches each stage into the results table. Video clip

Results Incident Start bike Leaps bike over hedge Bike swerves in front of semi Semi hits first car Bike goes down ramp Bike stops near bridge Speed (m/s) 6 9 Time(s)     Incident We first see Terminator Terminator shoots at gate lock Terminator’s bike drops into drain Semi’s tire is burst Semi explodes Speed (m/s) 12 Time (s)    

Analyze Data Convert all times to seconds. Plot results on a speed - time graph. Time goes on the x-axis; this is the independent variable. Speed goes on the y-axis (dependent axis). Label each point that John changes motion: A, B, C, D, E, F, G, H and I. Point A is at time 0,speed 0. Pre-AP: Divide the area below the graph line into five triangles and 4 rectangles.

Plot the Data What’s wrong with this graph?

Identify areas of “acceleration”, “deceleration”, and “at rest”. Graphs need title, axis labels and units Identify areas of “acceleration”, “deceleration”, and “at rest”.

PreAP Extenstion Divide graph into 4 rectangles and 5 triangles Task: To calculate the distance travelled we need to calculate the area under each slope. Divide graph into 4 rectangles and 5 triangles A graph to show Speed v Time for Connor's bike ride 2 4 6 8 10 12 14 50 100 150 200 250 300 Time (s) Speed (m/s) Remember area of a rectangle is ? Area = length x breadth Area of a triangle is ? Area = ½( length x breadth)

Area between 0-15 seconds = ½(15x6) = 45meters Area between 23 - 46seconds = ½(3x23) + (6x23) = 69 + 138 = 144meters Area between 46 - 65 seconds = (9x19) = 171meters
