For today's physics class we continued on working on the Centripetal Force Lab. It seems as though most people finished gathering their data and started to answer This lab shows the relations between centripetal force and speed. After writing down the data from the lab procedures, we begin to answer the questions stated in the booklet. The accuracy of the data might produce a variety of different results for this lab, however they should all be relatively close. It is imperative to keep close attention to the lab beforehand so that answering the questions will be easier.The data of the graphs provided us with the information to conclude that there is a power relation between force, speed an speed squared. Even though the shape of the two graphs are different they both illustrate that there is a power relation between their variables.
Question 1 and 3 of the booklet tells us to graph our data, with force as our independent variable and speed or speed squared as our dependent variable.
Questions 2 and 4 asks us what the relationship between the two variables are. It is shown that speed and speed squared have a power relation to force.
Question asks how if the formula Fc = mv^2/r supports the data we have gathered from the experiment. Since both mass and radius does not change it is clear that the formula is supposed to support the gathered data.
Also we were supposed to work on page 17 and 18, with the answers posted on page 25
and pages 21 and 22. Finishing all of these would be good practice and also would be good so that there will be lessened homework during spring break. That is all I have to say for this scribe.

Thanks Arveen. Graph 1 results in a parabola curve; a possible power relationship between F and v. Graph 2 results in a straight line which proves that the relationship between F and v is a power relationship. That's why you squared speed for the 2nd graph.
