Question

Objective: Determining the acceleration and velocity of an object during free fall.

Data: Acceleration of a metal ball free falling from various heights

D(m)	T(s)	G(m/s^2)	V(avg)	V(impact)	%Error
0.20m	.2079s	9.3m/s^2	0.96	1.9	5.10%
0.40m	.2873s	9.7 m/s^2	1.39	2.8	1.02%
0.60m	.3536s	9.6m/s^2	1.69	3.4	2.04%
0.80m	.4072s	9.6m/s^2	1.96	3.9	2.04%
1.00m	.4508s	9.8m/s^2	2.22	4.4	0%

1.) Write a conclusion about the lab. Compare your calculated v(avg) with the average of v(impact). Are they the same? Explain why it is different. Compare your calculated g with the theoretical g=9.8m/s^2 using percent error formula. Is your results close to expected values? What are the sources of error?

2.) What kind of graph, if any, should be used?
