Momentum Equation - Linear And Angular Conservation

Thumbnail

Linear and angular momentum has certain properties. Here we explore momentum's equations, rate of change, conservation, and link to torque and impulses.

Continuity Equation for Fluids in Different Coordinate Systems

Thumbnail

The continuity equation for fluids can be expressed in cartesian, cylindrical, or spherical coordinates, each with distinct properties and formulas.

Undamped and Damped Oscillations in Free Vibration

Thumbnail

Free vibration occurs when a spring-mounted system oscillates without external forces. Let us solve the formulas and equations of free vibration.

Relative Motion, Velocity, and Acceleration

Thumbnail

Two moving objects' motion relative to each other dictates the dynamics of their relative position, velocity, and acceleration.

Allowed, Forbidden, Fermi, and Gamow-Teller Beta Decay Transition

Thumbnail

The selection rules are important for classifying beta decay's transitions. They are based on the conservation of angular momentum and parity during decay.
