 1. Use the template here to write a paper about Using Golf Balls and Paper to measure the Acceleration of Gravity. Use the graphs you created yesterday as well as your data.When you are done, post a link to your paper here.Remember that you found this yesterday. Write about it in your results.11. Find the acceleration and final velocity for the golf ball and the paper at both heights.12. Compare the acceleration and final velocity of the golf ball and paper at each height.13. Explain why the acceleration and final velocity is different between the golf ball and the paper.From Yesterday2. Open a Google Doc and take a screenshot of each graph where you calculate the slope of the line. Include where you input the calculation and it says you are correct.3. Open one of your Logger Pro documents from yesterday.4. Click the Vy column so all of the numbers are selected.5. Insert > Graph to create a Velocity vs. time graph6. Arrange the two graphs so they are both visible on the screen.7. To find acceleration, you need to find the slope of the velocity vs. time graph. Select a good interval where the data looks good and smooth by dragging across the data in the graph.Then click the Linear Fit button.The slope of this velocity vs. time graph is the acceleration.8. Also, while you are here find the greatest velocity (negative due to direction) before the object hit the ground (it's not necessarily the last number).9. Click the graph and use Command-C to copy it.10. Then use Command-V to paste the graph and the linear fit into your document.11. Find the acceleration and final velocity for the golf ball and the paper at both heights.12. Compare the acceleration and final velocity of the golf ball and paper at each height.13. Explain why the acceleration and final velocity is different between the golf ball and the paper.Share your document with tonyfarley@mac.com
