Year 13 MechanicsMechanics Circular Motion
Purpose:
The purpose of this experiment is to introduce circular motion, by finding the mass of a bob and then verifying its mass using scales.

To find the speed of the spinning bob we use v = d / t
where d is v=2*pi*r/the circumference of the circle the bob makes when you swing it and t
Use Fc=mv^2
is the time it takes to complete one period.
so v = 2 ᴨ r / t
Use Fc = m v2 / r
