  • Speed, Velocity, Distance, Displacement and Acceleration

  • Project ObjectivesCalculate 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.

  • Project ObjectivesThe 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.

  • FocusImagine 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.

  • Title Slide of PresentationGroup Members Names

  • Slide # 1Using 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 distanceYour total travel time

    Slide RubricPoints3210Point BreakdownIncludes all necessary components.Omits 1 of the componentsOmits 2 of the componentsFails to include all the necessary components

  • Slide # 2Copy 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.

    Slide RubricPoints3210Point BreakdownAccurately place displacement vector. Use the definition of distance and displacement to develop your comparison. Detailed explanation of the earths 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 earths shape with respect to displacement. Omits one component.And undeveloped/incorrect explanations to one or more questions.

    Fails to include multiple components and/or incorrect, undeveloped answers to questions.

  • Slide # 3Use the your estimated traveling distance and elapsed time to find your average traveling speed according to Google. Include in this slide.

    Slide RubricPoints3210Point BreakdownAccurately 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. OrAccurately found your average speed. But failed to use equation editor to show your work. Included correct units.

    Omits one component.And undeveloped/incorrect explanations. Fails to include multiple components and/or incorrect, undeveloped answers to questions.

  • Slide # 4Research 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 RubricPoints3210Point BreakdownIncludes all necessary components.Omits 1 of the componentsOmits 2 of the componentsFails to include all the necessary components

  • Slide # 5Using 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.After constructing the graph you need to label each segment (you should have 7 segments) with:the slopethe distance and time elapsed during travel.the time elapsed during each stop.

    Slide RubricPoints3210Point BreakdownGraph 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. OrFailed to include one necessary component at one of the segments. Graph is inaccurate based on segments or slope. AndFailed to include one necessary component at more than one of the segments. Graph is inaccurate based on segments or slope. AndFailed to include multiple necessary components at more than one of the segments

  • Slide # 6Paste 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 RubricPoints3210Point BreakdownThe 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 componentsVectors are missing

  • Slide # 7From 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 RubricPoints3210Point BreakdownAccurately 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. OrAccurately found your acceleration for each scenario, but failed to use equation editor to show your work. Included correct units.

    Omits one component.And undeveloped/incorrect explanations. Fails to include multiple components and/or incorrect, undeveloped answers to questions.

  • Slide # 8Using 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.After constructing the graph you need to label each segment (you should have 3 segments) with:Positive, negative or zero accelerationSlope

    Slide RubricPoints3210Point BreakdownGraph 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. OrFailed to include one necessary component at one of the segments. Graph is inaccurate based on segments speed or slope. AndFailed to include one necessary component more than one of the segments. Graph is inaccurate based on segments speed or slope. AndFailed to include multiple necessary components at more than one of the segments

  • When you are finishedFeel free to ask me to look over your ppt before you submit it. Name your saved file like thisIf Mr. Gladding and Mr. Smith are in 2nd hour and worked on the project together their file would be named2.gladding.smithIf Mr. Gladding and Mr. Smith are in 3rd hour and worked on the project together their file would be named3.gladding.smithPlease attach the PPT to an email and send it to [email protected] put Physics 9 Project as the subject of the email.Check with me to see if I received it!
