Speed, Velocity, Distance, Displacement and Acceleration

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.

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.

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.

Title Slide of Presentation Group Member’s Names

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 Points 3 Point Breakdown Includes all necessary components. 2 Omits 1 of the components 1 0 Omits 2 of the components Fails to include all the necessary components

Slide # 2 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. Slide Rubric Points Point Breakdown 3 2 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 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 1 0 Omits one component. Fails to include And multiple undeveloped/in components correct and/or incorrect, explanations to undeveloped one or more answers to questions.

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 Points Point Breakdown 3 Accurately found your average speed. Used equation editor to show your work. Included correct units. 2 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. 1 0 Fails to include Omits one multiple components And undeveloped/inco and/or incorrect, undeveloped rrect explanations. answers to questions.

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 Points 3 Point Breakdown Includes all necessary components. 2 Omits 1 of the components 1 0 Omits 2 of the components Fails to include all the necessary components

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. � 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 Points Point Breakdown 3 2 1 0 Graph is inaccurate Graph is accurate, based on each segment is segments or slope. labeled with all 3 And Or components and Failed to include the slope reflects one necessary multiple necessary one necessary your average component at more components at component at one speed during travel. than one of the more than one of of the segments

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, SW, NW) and average speed away from the stopping point (you should have 4 vectors. Slide Rubric Points Point Breakdown 3 2 The 4 velocity Less than 3 vectors are velocity vectors are accurate and inaccurately labeled with speed and or direction according to Google maps route. 1 0 Vectors are inaccurate or missing key components Vectors are missing
