Title: How can I rearrange the Centripetal force equation?
Post by: dalyningkenk on Oct 3, 2013

Fc=m4(pi^2)r(f^2)

I need to rearrange that formula to make it equal to the slope of a graph. I need to then rearrange it so that I can find the mass.
Fc=Centripetal Force. (0.981)
m=Mass
(pi^2)= Pi squared.
r= radius of the string being swung (equal to 1).
(f^2)= Frequency squared. (1.585)
The slope of the graph was 1.6

You can divide the slope by (4(pi^2)r) and multiply this by 1000. This will give you your kilograms of the mass and them convert to grams

This will give you approximately 15.83 grams
