1. I believe the purpose of this lab was to demonstrate the difference between constant velocity and constant acceleration in a real life situation. This lab interactively showed how constant velocity and constant acceleration varied by the markings on the table.
2. The difference between constant velocity and constant speed is that constant velocity is where the speed does not change nor does the direction it is traveling. Constant speed is where the speed of an object is increasing evenly because of the acceleration increasing.
3. During this lab, there was a metronome that made a beat for every half second. My group and I propped a table so it was on a slope. We rolled the ball down the slope marking every half second where the ball rolled.
4. This proved that the ball was rolling at constant velocity. Each mark was measured and was evenly spaced out. With constant acceleration the distances between the marks gradually increased.
5. The formulas used in this lab were: to find velocity V= d/t
To find how far the object went we used d=1/2 at^2
And the equation of the line is y=mx+b
6. The line for constant velocity was a straight diagonal line that gradually increase with the same amount of time and distance. The constant accelerating graph increased speed over a shorter amount of time
7. When you entered a time into the x variable you get the distance at the rate of acceleration that was given.
8. In this lab I learned that its easier to graph your data and calculate the line it forms. I also learned that you must repeat an experiment multiple times to record results that support the problem of the lab.
