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…

Centripetal Force
Centripetal force is the force that is necessary to keep an object moving in a circular path. When an object is moving in a circle, it is constantly changing direction, which means it is also constantly accelerating. Centripetal force is the force that causes this acceleration. This is required by Newton’s Second Law: or, in…

Center of Mass
The center of mass is a concept in physics that describes the average position of an object or system of objects. It is an important concept because it allows us to simplify the description of a system by replacing it with a single point. This single point represents the average location of all the mass…

Capacitance
Capacitance describes the ability of a device to store electrical energy in the form of an electric charge. Capacitors, which are passive electronic components designed to store electrical energy, are widely used in electronic circuits for various purposes. Basic Understanding of Capacitance Capacitance is defined as the ratio of the electric charge stored in a…

Escape Velocity Calculator
The following escape velocity calculator can determine the theoretical escape velocity given two user inputs. The formula for escape velocity is: Generally, we calculate the escape velocity from the surface of a planet or moon. In this case, is just the radius of that body. However, if an object is already at a certain elevation,…

Buoyancy
Buoyancy is a fundamental concept in fluid mechanics that describes the upward force exerted by a fluid on an object that is partially or completely submerged. This force is responsible for objects appearing to weigh less in fluids and for objects floating or sinking. Basic Understanding of Buoyancy Buoyancy occurs due to the pressure difference…

Black Holes
Black holes are astronomical objects with an incredibly strong gravitational pull, resulting from a highly compressed mass in a small region of space. They play a significant role in our understanding of the universe, general relativity, and the nature of spacetime. Basic Understanding of Black Holes Black holes form when a massive object, such as…
