System of Particles and Rotational Motion
Centre of mass, torque, angular momentum and rotational dynamics explained in simple terms.
1.Introduction to System of Particles
A simple introduction to what a system of particles means and how we study the combined motion of many particles.2.Centre of Mass
Understand the centre of mass as the effective point where the entire mass of a body appears to act.3.Centre of Mass of Simple Bodies
Learn how to find the centre of mass of regular shapes like rods, discs and spheres.4.Linear Momentum of a System
A simple explanation of how the total momentum of a system of particles is calculated.5.Motion of Centre of Mass
Understand how the centre of mass of a system moves even if individual particles move differently.6.Conservation of Momentum
Learn why momentum remains conserved in a system when no external force acts on it.7.Torque
A beginner-friendly explanation of torque as the turning effect of a force.8.Moment of Inertia
Understand moment of inertia as the rotational analogue of mass and why it depends on mass distribution.9.Radius of Gyration
Learn how radius of gyration helps express the distribution of mass for rotational motion.10.Theorems of Moment of Inertia
Parallel and perpendicular axis theorems explained in simple language.11.Angular Velocity and Angular Acceleration
Understand rotational motion using angular velocity and angular acceleration.12.Angular Momentum
Learn about angular momentum as the rotational equivalent of linear momentum.13.Conservation of Angular Momentum
Understand how and why angular momentum remains constant when no external torque acts.14.Rolling Motion
Learn how objects like wheels roll without slipping, combining translation and rotation.15.Rotational Kinetic Energy
Understand how rotating bodies possess kinetic energy similar to moving bodies.16.Dynamics of Rotational Motion
Study how torque causes angular acceleration and influences rotational motion.
