Homework Statement
Hi,
I have been asked to find the moment of inertia of a rolling ball. The ball can be any size and radius. I have chosen a solid ball.
The experiment says that I should roll the ball down a ramp and then measure the time it takes for the ball to roll from the end of the ramp to some fixed distance. I have done this and have the measurements from the experiment but now I do not know how to calculate the moment of inertia?
Homework Equations
I know that for a stationary solid ball the moment of inertia is (2/5)Mr^2. the experiment talks about using potential, rotational kinetic and translational energy?
The Attempt at a Solution
I really am confused about what the moment of inertia actually is!
Can anyone point me in the right direction?
Thank You
Dominic
