Speed, Velocity, Distance, and Acceleration Summative Assessment

Motion, Speed, Velocity, and Forces Unit P2.1A – Average Speed I can calculate the average speed of an object when given data for time and position.   P2.1C – Line Graphs I can create line graphs using measured values of position and elapsed time. P2.1D – Motion I can describe and analyze the motion of an object when given a position-time graph. P2.2A – Differentiation of Measurements I can differentiate between distance, displacement, speed, velocity, and acceleration. P2.2B – Acceleration I can use change of speed and elapsed time to calculate average acceleration. P2.2C – Velocity/Time Graphs I can use a velocity-time graph to describe and analyze the motion represented. P3.4B – Forces I can identify forces acting on objects moving with constant velocity.

Focus Imagine that you and your friend are planning your winter break road trip. If you had millions of dollars and no responsibilities where would you go? Choose anywhere in the continental United State. 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 Dansville Middle School (address at dansvilleschools.org) 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 # 2 Use the your estimated traveling distance to find your average traveling speed according to Google. Then include the velocity of your car at each point along your trip. Include in this slide.

Slide # 3 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 # 4 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 #5 Decide on a scenario where you have a balanced and unbalanced forces acting upon your car while driving. Explain what happens and how this affects your trip.

Slide # 6 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. And include your answer on this slide.

Slide # 7 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 acceleration Slope
