Pre-Lab Questionnaire Experiment 2 Galileo’s Inclined Plane 1. Draw a free-body diagram for the ball in the illustration of your laboratory apparatus shown in the handout. Show and label all forces acting on the ball. Add them vectorially to find the net force. Assume friction to be negligible. Use ruler. 2. Derive an equation for the net force. From this write an equation for the acceleration of the ball, a, in terms of gravity, g, and the angle of the incline, ! . 3. If you take two balls with masses m 1 and m 2 (m 1 >> m 2 ), and release them from the same height on two planes side by side, which ball arrives at the bottom first? Justify your answer. 4. Write an equation relating an object’s constant acceleration, a, distance travelled,

Unformatted text preview: d, and travel time, t. Reference your answer with the name of the book you are using, the page, and the equation number. 5. Using the equations from questions 2 and 4, find g in terms of t, d, and ! . 6. Consider the equation d = (2 m/s 2 ) t 2 . Plot this equation to scale on graph paper with d on the y-axis and t on the x-axis (d vs t). 7. Using the equation of question 6, plot d vs t 2 with d on the y-axis and t 2 on the x-axis. 8. Calculate the slope of the plot from question 7. What is its physical meaning? 9. From your answer to question 8 determine the acceleration a....
