Starting with Newton’s 2nd Law, derive an expression for torque t in terms of mass m, lever arm r and angular acceleration (and introduce I – “Rotational Inertia” or “moment of inertia”) 3. Compare Newton’s second law for linear motion and rotational motion. 4. The two definitions of torque: 5. Rotational …

In rotational motion, torque, τ = Iα where a is angular acceleration and 1is moment of inertia. Moment of inertia: It is defined as the quantity expressed by the body resisting angular acceleration which is the sum of the product of the mass of every particle with its square of a distance from the axis of rotation.

The formula is L=Iω, where L is angular momentum, I is rotational inertia (or moment of inertia), and ω is rotational speed. The object can change its rotational inertia (or moment of inertia) and when it does so, its rotational speed will change in such a way that the product of the two will remain the same.

In the first method, the moment of inertia is determined theoretically by applying the formula for the moment of inertia of a single disk to each of four disks and adding the results. In the second method, the moment of inertia is determined experimentally by measuring the acceleration produced by a constant torque on the body. 1Figure 1.

Like Newton's second law for translational motion, F = ma, the law for rotational motion is τ = Iα, where τ is the torque, I is the moment of inertia and α is rotational acceleration. For a single object with its mass located at one point on a rigid bar, the moment of inertia can be calculated using the formula I = mr2.

In the case of fine structure splitting (S>0), the total of line strength of all fine structure lines just equals to the rotational line strength given by above formulas with the quantum number J replaced by N, while the relative intensity (RI) of fine structure lines should be determined by the quantum angular momentum coupling formula (see ...
