What Does P Mean In Physics?

What is 1g gravity?

One g is the force per unit mass due to gravity at the Earth’s surface and is the standard gravity (symbol: gn), defined as 9.80665 metres per second squared, or equivalently 9.80665 newtons of force per kilogram of mass..

What is the trident a symbol of?

The trident is associated with the sea-god Poseidon and his Roman counterpart Neptune. This divine instrument is said to have been forged by the cyclopes. Poseidon struck a rock with his trident, causing a sea (or a saltwater spring, called the Erechtheis) to appear nearby on the Acropolis in Athens.

What does P stand for in physics?

momentumIn physics, there is a quantity that represents the product of mass and velocity of an object. That quantity is called as momentum. The popular equation for momentum according to the Newton’s law is that P=MV. Here, P stands for momentum, M stands for mass and V stands for velocity of an object.

What does N stand for in physics?

newton(s)In physics and engineering documentation, the term newton(s) is usually abbreviated N. One newton is the force required to cause a mass of one kilogram to accelerate at a rate of one meter per second squared in the absence of other force-producing effects.

What does H mean in a text?

(H) means “Cool Dude Emoticon (MSN)”.

What does H mean in physics?

Planck’s constantPlanck’s constant, (symbol h), fundamental physical constant characteristic of the mathematical formulations of quantum mechanics, which describes the behaviour of particles and waves on the atomic scale, including the particle aspect of light.

What does Q stand for in physics?

chargeq is the symbol used to represent charge, while n is a positive or negative integer, and e is the electronic charge, 1.60 x 10-19 Coulombs.

Is G positive or negative?

Explanation: g is a constant, and is always positive, so any time you see “g” in an equation, use 9.81 m/s2 . So, for example, for gravitational potential energy Ug=mgh , you will always use g=9.81m/s2 . −g is the free-fall acceleration.

How many G’s can kill you?

According to a recent article in Popular Science, 14 Gs of lateral acceleration can tear your organs loose from one another. Head-to-foot motion, meanwhile, plunges all the blood to the feet. Between 4 and 8 longitudinal Gs will knock you out.

What does Poseidon’s Trident stand for?

Trident is typically used to describe the weapon that characterizes Poseidon as the god of the sea. … For instance, the trident is featured in the Ukrainian coat of arms. The trident signified the domination of the seas across Roman, Greek, and Hindu mythologies.

What does the PSI symbol mean?

The symbol for psychology represents the penultimate letter of the Greek alphabet, psi, which is also the first letter of the Greek word psuche, meaning mind or soul, from which the term psyche arose; which in turn gave us the name of the discipline psychology which is most commonly defined as study of the mind.

What does ψ mean?

The letter Ψ means incorporeal. Corpus means body. … Psei (ψεῖ) is the name of the letter Ψ, literally “incorporeal essence (of) divine-power.” The original shape of the letter Ψ was angular, a combination of the letter Υ (“pure”) and the letter Ι (“divine-power”).

What is the G in physics?

In the first equation above, g is referred to as the acceleration of gravity. Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2. … There are slight variations in the value of g about earth’s surface.

What is K physics?

The symbol k is a proportionality constant known as the Coulomb’s law constant. The value of this constant is dependent upon the medium that the charged objects are immersed in. In the case of air, the value is approximately 9.0 x 109 N • m2 / C2.

What does I stand for in physics electricity?

Circuit Symbols. Potential difference, current & resistance. Potential difference (V) is the amount of joules per coulomb of charge, it is measured in volts (V). Current (I) is the amount of charge per second passing a point in a circuit, it is measured in amps (A).

What does lowercase p mean in physics?

p = pressure. p = momentum. p = 3.14. Pa = pascal (pressure)

What does F in physics mean?

F = force m = mass a = acceleration Newton’s Second Law. Here, F is the net force on the mass m. … p = momentum m = mass v = velocity The definition of momentum. It is conserved (constant) if there are no external forces on a system.

What does XI stand for in physics?

the initial positionx-i and it means the initial position).
