Mar 22 2019 · Rotational inertia plays the same role in rotational motion as mass plays in linear motion. Both are a measure of how much an object resists changing from uniform motion. In linear motion the inertia (how much the object will resist changing from uniform motion in a straight line at a constant speed) is just the mass (m).
