This video explains how the removal of mass affects an object's rotational inertia, demonstrating the calculation of percentage decrease in rotational inertia when an innermost or outermost particle is removed.

This content explains and solves a physics problem involving an inelastic collision in rotational motion. A uniform rod, pivoted at one end, collides with a putty ball that sticks to its end. The solution demonstrates how to calculate...

This content defines the total angular momentum (L) of a rigid body as the vector sum of the angular momenta of its constituent particles. It then extends Newton's Second Law to rotational motion, stating that the net external torque on...

This Free Response Question includes the following concepts: Center of Mass of a System of Particles, Translational and Rotational Kinetic Energy, Conservation of Linear and Angular Momentum, Angular Momentum of a System of Particles and...

Calculus based review of moment of inertia for a system of particles and a rigid object with shape, the derivation of rotational kinetic energy, derivations of the following moments of inertia: Uniform Thin Hoop about is Cylindrical...

This nugget introduced the system of particles, rigid bodies about the kind of motion of rigid body.

Three point objects are located at various locations on a Cartesian coordinate system. Mass 1, with a mass of 1.1 kg, is located at (1.0,1.5) m. Mass 2, with a mass of 3.4 kg, is located at (3.0,1.0) m. Mass 3, with a mass of 1.3 kg, is...

Calculus based review of conservation of momentum, the momentum version of Newton’s second law, the Impulse-Momentum Theorem, impulse approximation, impact force, elastic, inelastic and perfectly inelastic collisions, position, velocity...
