4025 Figure 12. Using the angle measuring tool to measure 20° angle of ramp. Figure 13. Base of ruler supported by small note pads to align ruler groove with groove in wooden board. 3. Place a piece of tape on your ramp at the height/location of your choice. This will be the starting line for releasing your marble/object. 4. Measure the length of your ramp from the starting line (tape) to the bottom of the ramp to 0.001 m and record. 5. Take a photo of your setup and paste it into your lab notebook. 6. Hold the marble at the starting line. 7. Release the marble and start the stopwatch simultaneously. Note: Gently release the marble. Do not throw or push the marble in any direction. Release quickly. 8. Stop the stopwatch as the marble reaches the end of the ramp. 9. Record the time to the nearest 0.01 seconds. Repeat this four more times, for a total of five trials. 10. Calculate the average time taken by the marble to roll down the incline and record. 11. Use x = x + üt to solve for the velocity of the marble at the bottom of the ramp (the final velocity) and record to 0.01 m/s. First list and label each variable (label your unknown variable with a question mark), then show the equation, then show your values plugged into the equation and solve. Draw a box around your result. Part 2: 12. Hold the marble at the same starting line used in part 1. 13. Release the marble, but this time don't start the stopwatch when you release the marble. Instead, start the stopwatch when the marble transitions from the bottom of the ramp to the ground. Note: Gently release the marble. Do not throw or push the marble in any direction. Release quickly. 14. Allow the marble to roll to a stop on its own and stop the stopwatch as soon as the marble comes to rest. 15. Record the time to the nearest 0.01 seconds. 16. Measure the distance that the marble traveled along the ground (from the bottom of the ramp to its ending position) and record. 17. Repeat steps 12-16 four more times, for a total of five trials. 18. Calculate the average time taken by the marble to roll from the bottom of the ramp to its stopping point and record. 19. Calculate the average distance traveled by the marble from the bottom of the ramp to its stopping point and record. 20. Use x = x + üt to solve for the velocity of the marble at the bottom of the ramp and record to 0.01 m/s. First list and label each variable (label your unknown variable with a question mark), then show the equation, then show your values plugged into the equation and solve. Draw a box around your result. 21. Compare your results from part 1 and part 2. Are they similar? (How do we compare two values to determine if they are similar?). 22. What are some possible experimental sources of error? 23. What could be done to improve this experiment? 24. Write a full conclusion for this lab, including procedure 1 and procedure 2 in your conclusion.
