Quiz Review
Speed, Velocity, Acceleration, and Graphing Quiz
Graphing Acceleration: Terminator 2 Chase

9. 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.

10. 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.

11. 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.

13. 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.

15. Plot the Data
What’s wrong with this graph?

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

17. 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

Remember area of a rectangle is ?
Area = length x breadth
Area of a triangle is ?
Area = ½( length x breadth)

18. Area between 0-15 seconds = ½(15x6) = 45meters
Area between seconds = ½(3x23) + (6x23) = = 144meters
Area between seconds = (9x19) = 171meters
