- Homework Statement
- I had a bit of confusion on the point of rotation of rolling bodies. When a body rolls, we apply the formula τ = Iα. But in order to compute the moment of inertia we need to know the point of rotation of the object. If the object rolls about it's bottom most point then we need to add a extra {MR}^{2} for most rolling bodies. So please explain how to determine the point of rotation for rolling bodies.
- Relevant Equations
- τ = Iα
