WebThe moment of inertia is the property of the object (like mass),which doesn't change when the place where the force is applied changes. ( 1 vote) Tyler Jeffries 6 years ago How come he didn't take gravity into account. Doesn't the first mass (3) have a force of 30 Newtons? Because 3kg * 10 m/s/s = 30 Newtons. WebThe moment of inertia is the quantitative measure of rotational inertia, just as in translational motion, and mass is the quantitative measure of linear inertia—that is, the more massive an object is, the more inertia it has, and the greater is its resistance to change in linear velocity.
