Test Preparation

Today's session is the first one for Rotational Motion. 
It involves revision of some old terms and introduction to Rigid Bodies and Axis of Rotation.

Understanding the Basics

This session is mainly focussed on understanding Moment of Inertia and pointers on it.

A few derivations have also been discussed.

Moment of Inertia Part 1

This session is also based on Moment of Inertia.

Derivations for a Rod, Hollow Sphere and Solid Sphere has been discussed.

Moment of Inertia Part 2

This session is also based on Moment of Inertia. It has the derivation of a new geometry called the Lamina.

It further involves the introduction of Theorems on Moment of Inertia which are useful for finding MI about any axis.

Moment of Inertia Part 3

This lesson involves a few questions on Moment of Inertia.

Moment of Inertia Part 4

This session includes the introduction of the topic Torque and it's application in Rotational Mechanics.

Torque

This session involves Rotation about a fixed axis. One point has been pivoted and the body is set in motion with this constraint.

Energy Conservation and Concepts on Circular motion have also been integrated into this class of Rotational Motion.

Hinged Body Motion

This session involves questions on Hinged Body Rotation. It also introduces the rotation of pulley in the usual Laws of Motion problems.

Hinged Body Rotation

This session is about Angular Momentum and it's significance in many problems.

Toppling of bodies due to forces or obstacles has also been discussed.

Angular Momentum

Angular Impulse has been discussed in this session. A few questions were also taken up and application of Angular Impulse was understood.

Conservation of Angular Momentum was also revised by a discussing a problem.

Angular Impulse

This session will introduce the Combination of both Translation and Rotational Motion. Analysis of this topic yields an important conclusion of considering this motion in the form of a superposition of the individual motions.

We also solved some problems to understand it.

Combined Rotation and Translation

This session includes Combined Rotation and Translation Motion. The theory given in the previous lesson has been put into application in this session.

Problems based on Particle Rod Collision have been solved and all the previous concepts have been put into use.

Combined Rotational and Translational

This session involves some problems based on Combined Motion. A problem on the collision of a plate and particle was solved. A few problem profiles on Rod have also been solved.

This session introduces another important concept in Rotational Mechanics known as Rolling Motion. The concept is followed by some questions and different conditions for Rolling Motion have been discussed.

Rolling Motion

This session includes some problems based on Rolling Motion and its integration with Mechanics.

Different profiles of problems can be made easily with this topics. I have managed to cover a few and discuss hw Rolling Motion can make a problem much more elegant.
