1:54 PM Mon Jun 20 There are two equations for centripetal acceleration. Which equation for centripetal acceleration agrees with the relationship shown in your centripetal acceleration vs radius graph? Why do you think so? Find the slope of the line of best fit for your graph and write an equation of the line in slopeintercept form. Don't forget to include units for both your slope and your yintercept. Compare the equation you chose in question 4 with the one you found in your graph in question 5. What does your slope represent? Use this to determine the period of the platform. Show all your calculations. Your platform was set with a constant angular velocity of 90 degrees/second. Describe, in your own words, what an angular velocity, u: = 90 degrees/second actually means? Determine how long it would take the ladybug to make one full rotation. Calculate the percent error between your calculated value for period from question 6 and the answer to question 7. Draw a Free Body Diagram for the ladybug as it revolves around the turntable. Label all forces and show where the centre of the platform is in your diagram. . What force(s) is/are responsible for generating the centripetal force? , What new questions do you have after doing this lab? If you could extend this lab what else would you like to nd out with this equipment? What new hypothesis could be tested? In one or two short sentences, summarize the key ndings of the lab. When you have completed this lab worksheet, submit it and your graphs to the UNIFORM ACCELERA TED MOTION LAB HAND-IN BOX
