Kinetic Energy of Rotation: Energy Due to Spinning

When an object rotates, it possesses rotational kinetic energy — the energy associated with its spinning motion. Just like a

Rolling Motion: A Blend of Rotation and Translation

Rolling motion occurs when an object, like a wheel or a ball, moves forward while rotating about its own axis.

Rotational Equilibrium: No Net Torque, No Angular Acceleration

Rotational equilibrium is the condition in which an object or system is not experiencing any net torque—meaning all the torques

Center of Mass: The Balance Point of a System

The center of mass of a system is the point at which the entire mass of an object or group

Simple Pendulum: Harmonic Motion at Small Angles

A simple pendulum consists of a mass (called a bob) suspended from a fixed point by a string or rod,

Coriolis Force: Deflection from Earth’s Rotation

The Coriolis force is a pseudo-force that appears in rotating reference frames, such as Earth. It causes moving objects to

Pseudo-Forces: Apparent Forces in Accelerating Frames

Pseudo-forces, also known as fictitious forces, arise when observing motion from a non-inertial reference frame—that is, a frame that is

Projectile Motion: Parabolic Paths Under Gravity

Projectile motion refers to the curved path an object follows when it is launched into the air and moves under

Terminal Velocity: When Falling Reaches a Limit

Terminal velocity is the maximum constant speed an object reaches as it falls through a fluid—usually air—when the downward force

Inelastic Collisions: Momentum Conserved, Energy Lost

An inelastic collision is a type of interaction where momentum is conserved, but kinetic energy is not. During such collisions,
