The hanging mass (m2) experiences only two forces – the downward pull of gravity and the upward tension force. Now the Newton’s second law equation (Fnet…
Torque is defined as force times distance, where the force acts perpendicular to the distance about a point of rotation. If the sum of the torques…
In an explosion, an internal impulse acts in order to propel the parts of a system (often a single object) into a variety of directions. After the explosion, the individual parts of the system (that is often a collection of fragments from the original object) have momentum. What is the equation for an explosion? Again…
Force is equal to mass times acceleration. This is really a mathematical equation, f = ma. This equation applies to launching the rocket off the launch pad. It is essential to understand that there are four basic forces operating on any object moving through the air. How do you solve rocket propulsion problems? What is…
Physics comes into play in basketball whenever a player jumps in the air to shoot or rebound. What enthusiasts call “hang time” — when a player appears frozen at the peak of his leap — is the result of projectile motion. What kind of physics is basketball? Parabolic motion (or projectile motion) Basketball is probably…
Where Do 12 Universal Laws Come From? The 12 universal laws originated from Source (also known as God, the Universe, Higher Power, etc.). Just like physical laws like the laws of gravity, these universal laws were not invented but rather discovered by humans through their observations and experiences. How many physics laws are there? 34…
The CPT theorem is a theorem for local relativistic quantum field theories in Minkowski space-time. Here, C means ‘charge conjugation’, P ‘parity transformation’ (‘space inversion’), and T ‘time inversion’; while C and P are implemented by ► unitary operators, T is implemented by an antiunitary operator. What is CPT theory? The CPT theorem says, roughly,…
Solid-Fuel Rocket. The oldest and simplest of the types of rockets use solid fuel for thrust. Liquid-Fuel Rocket. Liquid-fuel rockets, as the name suggests, use liquid propellants to create thrust. Ion Rocket. Plasma Rocket. What is the physics of rocket? A rocket in its simplest form is a chamber enclosing a gas under pressure. A…
In Physics, various symbols or notations are used to denote different quantities. The denotations make the representation of the quantities easier. What does F mean in physics? F = force m = mass a = acceleration Newton’s Second Law. Here, F is the net force on the mass m. W = mg. W = weight.…

A micro-mirror projector uses millions of microscopic mirrors to form the images that we see on the screen. This technology still uses a very bright lamp, in this case to shine light through a prism that splits it up into color beams. How does a projector work optics? Two converging lenses refract the light so…
For physicists, math is a tool used to answer questions. For example, Newton invented calculus to help describe motion. For mathematicians, physics can be a source of inspiration, with theoretical concepts such as general relativity and quantum theory providing an impetus for mathematicians to develop new tools. What topics of maths are used in physics?…
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…
1 fg = 10⁻¹⁵ g = 10⁻¹⁸ kg. A gram (g) is a unit of mass, one of the base units in CGS. It is also a decimal fraction of the base unit of mass in the International System of Units (SI) kilogram. What does FG mean in physics? Fg, abbreviation used in physics for…
Anything which gives out light rays is called object . ( eg – bulb, candle and etc. ) Image : is an optical appearance produced when light rays coming from an object are reflected from a mirror ( or when two light rays meet ) What is an image in physics class 10? Image :…
(a) If the incident rays are converging, we have a real object. (b) If the final rays are converging, we have a real image. (c) The image of a virtual object is called a virtual image. (d) If the image is virtual, the corresponding object is called a virtual object. What is meaning of virtual…
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…
