THEORY 2 2 gt = d 2 0 2 at t v = x + The distance  x  travelled by an object under the  constant acceleration:
Procedure 1. Weigh the masses of the steel balls. 2. Set d , the height to approximately 2.0 meters. 3. Measure the time (3 trials) for the 13mm steel ball to fall. Find the average time t avg and calculate t 2 avg 4. Perform step (3) for d = 1.75, 1.50, 1.25, 1.00, 0.75, and 0.5m 5. Repeat steps 2 through 4 for 16mm steel ball.

Unformatted text preview: 2. Plot a graph: d versus (t^2)avg. Draw the straight line through the points of graphs (start from the origin of coordinates). 3. Measure the slope of the line and find the experimental value of g, and its errors. 4. Perform propagation of error for g. 5. Compare the values of g for balls of different masses. 6. Find (or calculate using appendix G) the actual value of g for our location. Refer to the source 7. Compare your experimental value of g with the actual one using number line and calculate %err. 8. Discuss the sources of error and its influence on deviation the graph from the straight line. 9. Answers on given questions (p. 8)....
