A wheel and axle is a simple machine that consists of two connected rings or cylinders, one inside the other. Both rings or cylinders turn in the same direction around a single center point. The inner ring or cylinder is called the axle, and the outer one is called the wheel. What is a wheel […]
The common symbol for energy is the uppercase letter E. The standard unit is the joule, symbolized by J. One joule (1 J) is the energy resulting from the equivalent of one newton (1 N) of force acting over one meter (1 m) of displacement. There are two main forms of energy, called potential energy […]

The static pressure is responsible for much of the force on the duct walls. However, dynamic (velocity) pressure introduces a rapidly pulsating load. Static pressure. Static pressure is the measure of the potential energy of a unit of air in the particular cross section of a duct. What is the difference between velocity and velocity […]
In high energy particle physics, specifically in hadron-beam scattering experiments, transverse momentum distributions (TMDs) are the distributions of the hadron’s quark or gluon momenta that are perpendicular to the momentum transfer between the beam and the hadron. Why is transverse momentum important? The component of momentum transverse (i.e. perpendicular) to the beam line. It’s importance […]
Temporal distribution of earthquakes, especially so-called characteristic earthquakes recurring on a specific fault or fault segment, often represented by a renewal process. It is defined as a series of events in which interevent times are independently and identically distributed. What is temporal distribution of rainfall? The temporal rainfall distribution is usually expressed as the rainfall […]
Thales was a Milesian philosopher credited with what is often described as the “discovery of nature,” or the realization of the fact that natural phenomena are explicable in terms of matter interacting according to natural laws. What is the meaning of Thales? Definitions of Thales. a presocratic Greek philosopher and astronomer (who predicted an eclipse […]
Constructive and destructive interference of light waves is also the reason why thin films, such as soap bubbles, show colorful patterns. This is known as thin-film interference, because it is the interference of light waves reflecting off the top surface of a film with the waves reflecting from the bottom surface. What is the shape […]
The SI unit of temperature as per the International System of Units is Kelvin which is represented by the symbol K. The Kelvin scale is widely accepted or used in the field of science and engineering. What are the 4 types of temperature scales? Fahrenheit Scale. โขโขโข The Fahrenheit scale of temperature is the common […]
A system, as it is defined in physics or chemistry, is nothing more than a collection of objects (or smaller systems) that can be identified. Usually, the word “system” refers to a collection that makes thinking about a problem more convenient. The surrounding is everything else that is not the system defined. What is a […]
The importance of resonance is that the circuit can either absorb or dissipate the maximum amount of energy at resonance. One practical example is used in a radio receiver. Many the frequencies from different radio stations are impinging on the radio’s antenna at the same time. What is a resonant frequency in physics? , in […]
SOUND PROPAGATION The TRANSMISSION of acoustic energy through a medium via a SOUND WAVE. See: SOUND, SPEED OF SOUND. What is a propagation in physics? The act or process of propagating, especially the process by which a disturbance, such as the motion of electromagnetic or sound waves, is transmitted through a medium such as air […]
Slope is denoted by ‘m’. Slope is calculated by finding the ratio of the “vertical change” to the “horizontal change” between any two distinct points on a line. What is a slope in physics? Slope, or m as we often write it in equations, describes the way a function changes. The slope of a function […]
And, the simple harmonic motion is always oscillatory. Periodic motion examples are the motion of the hands of a clock, the motion of the wheels of a car, etc. Simple harmonic motion examples: the motion of a pendulum, motion of a spring, etc. Learn the difference between Periodic and Oscillatory Motion here. What is the […]
The layer of charge separation or voltage difference between an electrode material and a relatively concentrated electrolyte, which typically depends on the adsorption of solvent dipoles (typically water molecules) and results from their individual electrostatic dipole moment charge difference. What is the separation of charge called? Dipole moments occur when there is a separation of […]
Reliability refers to how consistently a method measures something. If the same result can be consistently achieved by using the same methods under the same circumstances, the measurement is considered reliable. You measure the temperature of a liquid sample several times under identical conditions. What is reliability and example? What is Reliability? Reliability is a […]
Definition of reflection grating : a diffraction grating whose lines are ruled on a mirror surface. What is grating equation in physics? d = frac 1 N , where N is the grating constant, and it is the number of lines per unit length. Also, n is the order of grating, which is a positive […]
In a quasi-static process, the path of the process between A and B can be drawn in a state diagram since all the states that the system goes through are known. In a non-quasi-static process, the states between A and B are not known, and hence no path can be drawn. Is also called quasi-static […]
When each point on a plane of a two-dimensional coordinate system is decided by a distance from a reference point and an angle is taken from a reference direction, it is known as the polar coordinate system. Pole = The reference point. How are polar coordinates defined and used? The polar coordinate equation is (r,ฮ) […]
It is in this regard that some people use the term “physics envy” to describe how many social sciences, including psychology, wish they had more scientific prowess (Clarke & Primo, 2012; Fish, 2000). What is envy in science? “Physics envy” refers to the envy (perceived or real) of scholars in other disciplines for the mathematical […]
The coefficient of friction is dimensionless and it does not have any unit. It is a scalar, meaning the direction of the force does not affect the physical quantity. The coefficient of friction depends on the objects that are causing friction. The value is usually between 0 and 1 but can be greater than 1. […]
