Escape Velocity
Introduction Escape velocity is the minimum speed an object must have in order to escape the gravitational pull of a planet or other body without further propulsion. Essentially, it is the speed needed to break free from the gravitational field of a massive body. Calculation The escape velocity () from the surface of a spherical…

Simple Harmonic Motion
Introduction Simple Harmonic Motion (SHM) is a type of periodic motion where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement. It is an important concept in physics due to its wide applicability in various phenomena such as pendulums, spring-mass systems, and oscillations in electrical…

Speed
Introduction Speed is a fundamental concept in physics that describes how quickly an object moves. It is a scalar quantity, meaning it has magnitude but no direction. The SI unit of speed is the meter per second (). Velocity, is speed plus some direction. Velocity is a vector quantity. Average and Instantaneous Speed Average speed…

Waveguide
Introduction A waveguide is a physical structure that is used to control and direct electromagnetic waves. They are commonly used in microwave communications, broadcasting, and radar installations. Basic Definition A waveguide is typically a hollow metal tube or dielectric slab that confines electromagnetic waves to travel in a direction defined by its physical boundaries. The…

Velocity
Velocity is a vector quantity that describes the rate at which an object changes its position. It is defined as the displacement of an object per unit of time and has both magnitude and direction. Velocity is often measured in meters per second (m/s), but other units such as feet per second (ft/s) or miles…
