1. Speed, Velocity, Distance, Displacement and Acceleration

2. Project Objectives Calculate the average speed of an object using the change of position and elapsed time. Create line graphs using measured values of position and elapsed time. Describe and analyze the motion that a position-time graph represents, given the graph.

3. Project Objectives The motion of an object can be described by its position and velocity as functions of time and by its average speed and average acceleration during intervals of time. Distinguish between the variables of distance, displacement, speed, velocity, and acceleration. Use the change of speed and elapsed time to calculate the average acceleration for linear motion. Describe and analyze the motion that a velocity-time graph represents, given the graph.

4. Focus Imagine that you and your friend are planning your spring break road trip. If you had millions of dollars and no responsibilities where would you go? The project below is designed for such a scenario. It is also designed to open your eyes to all the physics involved with traveling. You will be asked to pick a dream and discuss the different physics involved in your travels.

5. Title Slide of Presentation Group Member’s Names

6. Slide # 1 Using Google Maps, map out a route from Lowell High School (address at lowellschools.com) to your dream travel destination. ◦ Take a screen shot showing the entire route and include it in this slide. ◦ On the map, insert a text box that explains:  Your total distance  Your total travel time Slide Rubric Points3210 Point Breakdown Includes all necessary components. Omits 1 of the components Omits 2 of the components Fails to include all the necessary components

7. Slide # 2 Slide Rubric Points3210 Point Breakdown Accurately place displacement vector. Use the definition of distance and displacement to develop your comparison. Detailed explanation of the earth’s shape and its effect on your displacement. Poor placement of displacement vector. No use of the definition of distance and displacement to develop your comparison. Short explanation of earth’s shape with respect to displacement. Omits one component. And undeveloped/in correct explanations to one or more questions. Fails to include multiple components and/or incorrect, undeveloped answers to questions. Copy your map onto this slide. Accurately Place your displacement vector on your map. Insert a text box and explain: ◦ how your total distance traveled be different than your total displacement. Which will be greater? Insert another text box and explain how the spherical shape of the earth would have an effect on your displacement vector.

8. Slide # 3 Use the your estimated traveling distance and elapsed time to find your average traveling speed according to Google. Include in this slide. Slide Rubric Points3210 Point Breakdown Accurately found your average speed. Used equation editor to show your work. Included correct units. Included incorrect average speed but used equation editor to show your work. Included correct units. Or Accurately found your average speed. But failed to use equation editor to show your work. Included correct units. Omits one component. And undeveloped/inco rrect explanations. Fails to include multiple components and/or incorrect, undeveloped answers to questions.

9. Slide # 4 Research 2 other destinations you want to stop at on the way to your final destination. If you have choose a nearby destination these could include stops for gas or food. Insert these destinations into Google maps and re-enter your route information into Google. Take a screen shot and place your map with your new updated route on this slide. Slide Rubric Points3210 Point Breakdown Includes all necessary components. Omits 1 of the components Omits 2 of the components Fails to include all the necessary components

10. Slide # 5 Using Geogebra, construct a distance-time graph including a point at each stop. Keep in mind your slope should reflect your average speed. Also assume you are traveling non-stop back home.Geogebra After constructing the graph you need to label each segment (you should have 7 segments) with: ◦ the slope ◦ the distance and time elapsed during travel. ◦ the time elapsed during each stop. Slide Rubric Points3210 Point Breakdown Graph is accurate, each segment is labeled with all 3 components and the slope reflects your average speed during travel. Graph is inaccurate based on segments or slope. Or Failed to include one necessary component at one of the segments. Graph is inaccurate based on segments or slope. And Failed to include one necessary component at more than one of the segments. Graph is inaccurate based on segments or slope. And Failed to include multiple necessary components at more than one of the segments

11. Slide # 6 Paste your map from slide 4. On your map, Place and label a velocity vector at each stop showing your direction (N, S, E, W, NE, SE, SW, NW) and average speed away from the stopping point (you should have 4 vectors. Slide Rubric Points3210 Point Breakdown The 4 velocity vectors are accurate and labeled with speed and direction according to Google maps route. Less than 3 velocity vectors are inaccurately labeled with speed or direction according to Google maps route. Vectors are inaccurate or missing key components Vectors are missing

12. Slide # 7 From a stoplight, assume that it takes your vehicle 10 seconds to reach your average speed. What is your acceleration rate in ? After driving at your average speed for one minute, the light in front of you turns red and it takes your vehicle 8 seconds to come to a complete stop. What is your acceleration rate in ? Answer the above two questions, showing your work in equation editor. And include your answer on this slide. Slide Rubric Points3210 Point Breakdown Accurately found your acceleration for each scenario. Used equation editor to show your work. Included correct units. Included incorrect acceleration for each scenario, but used equation editor to show your work. Included correct units. Or Accurately found your acceleration for each scenario, but failed to use equation editor to show your work. Included correct units. Omits one component. And undeveloped/inco rrect explanations. Fails to include multiple components and/or incorrect, undeveloped answers to questions.

13. Slide # 8 Using Geogebra, construct a Speed-time graph representing the scenarios from slide # 7. Place a point at each place your acceleration changes (i.e. goes from positive to zero ect.) Keep in mind your slope should reflect your acceleration and lines should reflect your speed.Geogebra After constructing the graph you need to label each segment (you should have 3 segments) with: ◦ Positive, negative or zero acceleration ◦ Slope Slide Rubric Points3210 Point Breakdown Graph is accurate, each segment is labeled with both components the slope reflects your acceleration and lines reflect your average speed during travel. Graph is inaccurate based on segments slope or speed. Or Failed to include one necessary component at one of the segments. Graph is inaccurate based on segments speed or slope. And Failed to include one necessary component more than one of the segments. Graph is inaccurate based on segments speed or slope. And Failed to include multiple necessary components at more than one of the segments
