A set of some of the most common physics formulas and constants.

• It provides Physics formulas and constants for calculation porpuses.
• It allows to create some objects to simplify some calculations (see example).
• It also provides some common Math formulas in Physics.

• Force, Speed, Time, Work, Acceleration, Density, Intensity, Power, Momentum
• Potential Energy, Mechanical Energy, Kinetic Energy, Frequency, Doppler Effect
• Centripetal Acceleration, Centripetal Force, Pendulum Period, Projectile motion equations

• Potential Gravitational Energy, Universal Gravitational Law, Gravitational Field
• Escape Speed

• Stokes's Law, Hagen-Poiseuille's Law

• Ohm's Law, Capacitance, Voltage, Coulomb's Law, Energy Density
• Electric Field, Eletric Potential Energy Difference.

• Gay-Lussac's Law, Net Heat Energy, Heat Flux, Eletric Field Flux, Joule Heating

• Lorentz Factor, Relativistic Time, Relativistic Distance, Relativstic Mass, Relativistic Momentum
• Photoelettric Effect, Drift Speed.

• Download the 'formulas' package to get the Physics formulas:

go get -u github.com/Gabri432/gophysics/formulas

• Download the 'constants' package to get the Physics constants:

go get -u github.com/Gabri432/gophysics/constants

• Download the 'mathem' package to get the Mathematical functions and constants of the library

go get -u github.com/Gabri432/gophysics/mathem

• Example of usage

package main

import (
    "fmt"
    "github.com/Gabri432/gophysics/constants"
    "github.com/Gabri432/gophysics/formulas"
)

func main() {
    fmt.Println(constants.C)   // Write a constant
    fmt.Println(formulas.Force(3, 4))   // Call a function
    myPlanet := formulas.PlanetBody{Mass: constants.EARTH_MASS, Radius: constants.EARTH_RADIUS} // Create a custom object
	fmt.Println(myPlanet.EscapeSpeed())  // Call object methods to ease some calculations
}

=== Output ===
299792453  
12 N       <<< When calling functions their output is the value and the measurement unit
11183.719071923773 m/s

• Using mathematical functions

import (
    "fmt"
    "github.com/Gabri432/gophysics/mathem"
)

func main() {
    fmt.Println(mathem.Pi) // Writing a constant
}

=== Output ===
3.1415926535
