Radius of Gyration Class 11| Definition & Equation| JEE & NEET

Radius of Gyration Class 11 As a measure of the way in which the mass of a rotating rigid body is distributed with respect to the axis of rotation, we define a new parameter known as the radius of gyration. It is the distance whose square when multiplied with the mass of the body gives the moment of inertia of the body about the given axis. For a body of mass $M,$ if $K$ is radius of gyration $\mathrm{I}=\mathrm{MK}^{2}$ $\mathrm{K}=\sqrt{\frac{\mathrm{I}}{\mathrm{M}}} \quad \mathrm{K}=\sqrt{\fr...

Combine Translational and Rotational Motion | Physics 11, JEE & NEET

Here you will study about rolling without slipping Motion and Combine Translational and Rotational Motion. Combine Translational and Rotational Motion If in case of rotational motion of a body about a fixed axis (called spining) the axis of rotation also moves, the motion is called combined translatory and rotatory motion. Motion of rolling wheel and flying saucer can be examples of this type of motion. Total K.E. $\quad \mathrm{E}_{\mathrm{T}}=\mathrm{E}_{\mathrm{t}}+\mathrm{E}_{\mathrm{r}}$ $=...

Kinetic Energy of a Rotating Body | Physics 11, JEE & NEET

Here you will study work done in rotation motion and Kinetic Energy of a Rotating Body. WORK DONE IN ROTATORY MOTION When a body rotates under action of torque then work is done by torque. If $\tau$ is uniform and body rotates by an angle $\theta$ then Work done = $\tau \theta$ But if $\tau$ depends on $\theta \quad$ for example in case of twisting a wire, $\tau=c \theta \quad$ where $c$ is const. $\begin{array}{ll}{\text { Then work done }} {\mathrm{dW}=\tau \mathrm{d} \theta \quad \text { (sin...

Conservation of Angular Momentum Examples | Physics 11

Here are the Conservation of angular momentum examples: (i) A point mass is tied to one end of a cord whose other end passes through a vertical hollow tube, caught in one hand. The point mass is being rotated in a horizontal circle. The cord is then pulled down so that the radius of the circle reduces. Here the force on the point mass due to cord is radial and hence the torque about the center of rotation is zero therefore, the angular momentum must remain constant as the cord shortend. As cord ...

Parallel and Perpendicular Axis Theorem of Moment of Inertia

Theorems of Moment of Inertia: Parallel and Perpendicular Axis Theorem Perpendicular axis theorem: [Only for laminar bodies] The sum of moments of inertia of a laminar body about any two mutually perpendicular axis in its plane is equal to its moment of inertia about an axis perpendicular to its plane and passing through the point intersection of the first two axis. $\mathrm{I}_{z}=\mathrm{I}_{x}+\mathrm{I}_{y}$ This theorem works only for two dimensional object only. (Circular disk, ring, table...

Physical Significance of Moment of Inertia for Class 11, JEE & NEET

Lets study about Moment of Inertia of a Rigid Body and Physical Significance of Moment of Inertia here. MOMENT OF INERTIA OF RIGID BODY It is the property of a body due to which it opposes any change in its state of rest or uniform rotation. Analytically for a particle of mass m rotating in a circle of radius R, moment of inertia of a particle of mass m about the axis of rotation is given by: $\mathrm{I}=\mathrm{mR}^{2}$ . . . . .(1) So for a body made up of number of particles (discrete distrib...
