Fc Right Round The Lab
LEARNING GOALS OF THIS LAB:
1. Use your knowledge of Newton’s laws and circular motion to make a prediction about the outcome of an experiment.
2. Apply your knowledge of Newton’s laws to solve a practical problem.
3. Use two independent methods to determine a quantity experimentally.
4. Evaluate simplifying assumptions that you use in your mathematical procedure.
Student Responsibilities.
Record Data in easliy viewable tables
Show a sample calculation for one trial
Calculate % error
state reasons for discrepancies

Are we supposed to be doing this in the cafeteria while your absent?

WHat is an example of a practical problem that we could too? Kind of confused
ReplyDeleteWhat size radius does a curve need to have so that cars can safely negotiate it in inclement weather( u~.2. Like we did in class.
ReplyDeleteso for the lab form many of these numbers should be the same, correct? for example F(tension) and Fc?
ReplyDeleteYo Marty, That's right
DeleteHey Mr. Crane, I was not in class on Friday when everyone did the lab. What would you like me to do?
ReplyDeleteHey Mr.Crane
ReplyDeleteI was out on Friday when we did the lab and I would just like to know like Arsene what you would like me to do as we do not have access to the materials during class and i just want to make sure that I do not get a zero at the end of the marking period if you aren't here.
Thanks
Rob
P.S. Congratulations
I wasn't in school on monday, and my lab partner (Jennifer Strenger) was also absent, and we didn't finish the lab on friday. I looked for you at lunch today, but you weren't in my room. I was also wondering what I should do. Jen will not be in school until Thursday so will I have to finish the lab by myself tomorrow? Also I just wanted to know when I would be able to finish it.
ReplyDeleteWhat is the equation we are suppose to use to solve for Accerlation because I can't find it in my notebook.
ReplyDeleteJoe R
Centripetal Acceleration= V^2/r
Deletei thought centripetal force was Fc=ma
ReplyDeletecentripetal force is Fc=mv^2/r which is technically also ma because centripetal acceleration is v^2/r. it's just more specific for when the object is going in a circle
DeleteIs the centripetal acceleration calculated from the Fc we found or what it should be, Fg?
ReplyDeleteCentripetal Acceleration= V^2/r
ReplyDeleteFc=ma= mv^2/r, a =v^2/r . . . that seems right?
DeleteMr. Crane if you found two velocities instead of Fc and Ft where do you put that in the Lab data form
ReplyDeleteJoe R
were we supposed to include units?
ReplyDeleteHunter Hurst
er guess not, i resubmitted mine sorry!
ReplyDeleteHunter Hurst
I sumitted a second set of results - one with the units and one without
ReplyDeleteChloe Molineaux
we did the first one wrong so its the second one that counts
DeleteHunter Hurst
are Fg and Ft in newtons?
ReplyDeletefor acceleration . . . F=ma . . . and it says centripetal so do we use Ft?
ReplyDeleteDoes gravity contribute to this at all because f=f and gravity can be calculated technically?
