Rolling Motion (Rolling without Slipping)
Rotation ยท Class 11
๐ก Master the concept of the Instantaneous Axis of Rotation (IAR) and understand when to apply energy conservation versus dynamic force/torque equations for efficient problem-solving.
Moment of Inertia + Parallel Axis Theorem
Rotation ยท Class 11
๐ก Master the standard MOI formulas for common shapes and meticulously practice the correct application of the Parallel Axis Theorem, ensuring 'd' is always the distance from the CM axis.
Elastic & Inelastic Collisions
Centre of Mass & Collisions ยท Class 11
๐ก Always begin collision problems by identifying the type of collision (elastic, inelastic, perfectly inelastic) and applying conservation of linear momentum; then, selectively apply kinetic energy conservation or the coefficient of restitution as appropriate.
