Answer:
False
Explanation:
The moment of inertia for a rigid body is given by
where
is the density distribution of the object
r is the distance from the axis of rotation of the object
Essentially, the moment of inertia does not depend only on the mass of the object, but also on its shape. For example: for a solid cylinder, the moment of inertia derived from the formula above is
where M is the mass of the cylinder and R is its radius. As we see, I (moment of inertia) does not depend on the mass only: therefore, if two objects have same moment of inertia, this does not imply that they also have the same mass.
