What is Alpha Beta Gamma called?

What is Alpha Beta Gamma called?

Alpha radiation is the name for the emission of an alpha particle in fact an helium nuclei, beta radiation is the emission of electrons or positrons , and gamma radiation is the term used for the emission of energetic photons.

What is U called in physics?

Symbol. μ (statistics) population mean. (physics) coefficient of friction.

What is μ physics?

Coefficient of friction, ratio of the frictional force resisting the motion of two surfaces in contact to the normal force pressing the two surfaces together. It is usually symbolized by the Greek letter mu (μ).

What does R stand for in physics?

R = resistance. R = molar gas constant.

What is r in physics gravity?

Where M is the mass of the Earth, r the radius of the Earth (or distance between the center of the Earth and you, standing on its surface), and G is the gravitational constant.

What does V stand for in physics?

electric potential difference volt

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. The useful thing about momentum is its relationship to force.

What are the 3 laws of physics?

Newton’s three laws of motion may be stated as follows: Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it. Force equals mass times acceleration [ ]. For every action there is an equal and opposite reaction.

What is the difference between R and R in physics?

The difference is r=scalar and R=vector.

What does U mean in physics velocity?

u is initial velocity in m/s. t is time ins. For example, a car accelerates in 5 s from 25 m/s to 3 5m/s. If there is achange in speed, direction or both, then the object has achanging velocity and is said to be undergoing anacceleration.

What does U mean in velocity?

u is initial velocity in m/s. t is time in s. For example, a car accelerates in 5 s from 25 m/s to 3 5m/s. Its velocity changes by 35 – 25 = 10 m/s.

What does S stand for in circular motion?

These angular variables are: Distance: s = rθ θ = angular position. Velocity: v = rω ω = angular velocity. Acceleration: at = rα; α = angular (tangential) acceleration.

What does Epsilon look like?

An uppercase Epsilon looks like a modern uppercase E in the English alphabet, but the lowercase Epsilon looks more like a reversed 3. The Greeks actually borrowed the symbol from the Phoenician alphabet, where it is used to represent the letter He.

What Epsilon means?

The greek letter epsilon, written ϵ or ε, is just another variable, like x, n or T. Conventionally it’s used to denote a small quantity, like an error, or perhaps a term which will be taken to zero in some limit.
