Physics 20 - Module 1 Kinematic Lab You will use the Projectile Motion lab from University of Colorado below to complete an investigation. A video describing the lab instructions can be viewed here. Part A: Determine the relationship between horizontal velocity and horizontal distance (range) 1. Choose the Intro Section of the simulation 2. Set the canon height to 10 m on the simulation and initial speed to 10 m/s. 3. Aim cannon horizontally (i.e. zero degrees) maintain this angle for part A of the lab 4. Fire the cannon and record the initial velocity, horizontal range and flight time using the purple Measure Tool after each firing in the table below. Ensure that your readings are from when the height is zero on the tool. 5. Make repeated firings but increase the velocity each time by 2 m/s until 20 m/s. (You may need to zoom out by clicking on the magnifying glass.) 6. Create a position (range) as a function of initial velocity graph. 7. Describe the shape of the graph and explain the significance of the shape. Explain what the graph shape tells you about the type of motion in the horizontal plane. 8. Analyze the graph. Determine the slope of the line and explain the significance (ie. relate it to a physics equation).Table 1: Initial velocity. flight time. and horizontal range for a projectile red from a height of 5111 Initial Velocity (mtg) Flight Time (3} Horizontal Range {ml Graph the data in order to describe the relationship between range vs initial velocity See rubric for graph requirements. Graph can be created by hand, but should be made in Excel or Google Sheets. There is a grid paper at the end of this document if needed. Analysis: . Draw a best-fit line. Determine the slope by hand using GRASP. (Do not use the equation generated from Google Sheets/Excel.) What does the slope represent? . State the shape of the graph, and relate the shape to an appropriate physics equation Part B: Determine the relationship between vertical height and flight time 1. Erase all the previous flight paths. Aim cannon vertically (ie. 90 degrees) and change the velocity to Om/s. Maintain these settings for part B of the lab 2. Change the height of the cannon to 5 m. 3. Fire the cannon and record the flight time using the purple Measure Tool after each firing in the table below. Ensure that your readings are from when the height is zero on the tool. 4. Make repeated firings but increase the height of the cannon each time by 2 m until 15 m. 5. Record the vertical height and flight time in the following table.Table 2: Flight times for projectiles fired vertically at 0 m/s from various heights Height (m) Flight Time (s)Create a ight time as a function of vertical height graph of your results. (Note: it will not be a straight line.) See rubric for graph requirements. Graph can be created by hand, but should be made in Excel or Google Sheets. There is a grid paper at the end of this document if needed.
