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,
