## What are the 3 laws of physics?

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

## What does U mean in physics velocity?

u is initial velocity in m/s. t is time in s.

## What is Newton formula?

Force (Newton) = Mass of body × Acceleration. Or, F = [M1 L0 T0] × [M0 L1 T-2] = M1 L1 T-2.

## What is the meaning of U in physics?

classical mechanics, U is often used to represent potential energy. Specifically, it’s used as a symbol for gravitational potential energy and elastic potential energy. – In electrodynamics, U is used to represent electric potential energy. – In thermodynamics, U is often used as the symbol for internal energy.

## What does G stand for in physics?

universal gravitational constantIn physics “g” means acceleration due to gravity. The variable g represents the gravitational field, which near earth is 9.8 ~ 10 N/kg. the variable g represents the free-fall acceleration. … ‘G’ stands for the universal gravitational constant/Newton’s constant.

## What is lowercase n in physics?

N = newton (force or weight) n = nano.

## How do you find N in physics?

The definition of a Newton, the standard unit of force, is N = kg * m/s^2.

## What does μ mean?

MicroMicro- (Greek letter μ or legacy micro symbol µ) is a unit prefix in the metric system denoting a factor of 10−6 (one millionth). Confirmed in 1960, the prefix comes from the Greek μικρό (mikró), meaning “small”. The symbol for the prefix comes from the Greek letter μ (mu).

## 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 V with a line over it mean in physics?

Speed and velocity are related in much the same way that distance and displacement are related. … Speed gets the symbol v (italic) and velocity gets the symbol v (boldface). Average values get a bar over the symbol.

## What does capital M mean in physics?

Originally Answered: What does M stand for in physics? M usually stands for mass or meters. The capital M is usually the mass of the larger object. It could also stand for the moment of force.

## What is V and U in light?

m = -v/u. Where v is the image distance and u is the object distance. Hence, the expression for magnification (m) becomes: m = h’/h = -v/u. Learn more about Reflection of Light here.

## How much is a Newton in KG?

1 N = 0.10197 kg × 9.80665 m/s2 (0.10197 kg = 101.97 g). The weight of an average adult exerts a force of about 608 N.

## Why does P stand for momentum?

Originally Answered: Why do we use (p) as the momentum symbol? It is because m was already taken for mass , for that matter all the other letters were taken. p is used because the word impetus formally in place ofmomentum comes from the latin, petere, hence we get p.

## What does Q mean 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.

## What is P physics?

Momentum is a measurement of mass in motion: how much mass is in how much motion. It is usually given the symbol p. … This simple relationship means that doubling either the mass or velocity of an object will simply double the momentum.

## What is this symbol ψ?

Psi /ˈsaɪ/ (uppercase Ψ, lowercase ψ; Greek: ψι psi [ˈpsi]) is the 23rd letter of the Greek alphabet and has a numeric value of 700. In both Classical and Modern Greek, the letter indicates the combination /ps/ (as in English word “lapse”). … The classical Greek letter was adopted into the early Cyrillic alphabet as “Ѱ”.

## What are the basic physics formulas?
