Problem: To determine the relationship between galaxy distance and velocity.
Hypothesis: Logically thinking I did not figure there to be any relationship between the distance of a galaxy and its velocity.
Procedure: We were provided with a list of data indicating the velocity and distance of certain galaxies. Using this information we plotted this data and drew a line of best fit. We then answered some questions about the relationship we found.
Data and Calculations: Are included on the hard copy of the lab that will be turned in on the day of the test.
Conclusion: We found that the relationship between the distance and velocity of a galaxy is direct which explains to us that objects in are galaxy that are further away are moving faster. This was my aha moment because I did not expect there to be a difference in velocity between galaxies of different distances from us. Some error is found in our graph because we estimated the velocity of each galaxy so each person’s estimate differs by ±2 or 3 km/s.
