Struct RelativisticBody 

pub struct RelativisticBody {
    pub rest_mass: f64,
    pub velocity: f64,
}

A body with scalar rest mass and signed velocity.

Fields

rest_mass: f64

Rest mass in kilograms.

velocity: f64

Signed velocity in meters per second.

Implementations

impl RelativisticBody

pub fn new(rest_mass: f64, velocity: f64) -> Option<Self>

Creates a relativistic body when rest_mass is finite and non-negative and velocity is finite with a magnitude strictly less than the speed of light.

pub fn beta(&self) -> Option<f64>

Computes the speed ratio magnitude β for the body’s current velocity.

pub fn lorentz_factor(&self) -> Option<f64>

Computes the Lorentz factor γ for the body’s current speed magnitude.

pub fn rest_energy(&self) -> Option<f64>

Computes the body’s rest energy in joules.

pub fn total_energy(&self) -> Option<f64>

Computes the body’s total relativistic energy in joules.

Examples

use use_relativity::{RelativisticBody, SPEED_OF_LIGHT};

let body = RelativisticBody::new(1.0, SPEED_OF_LIGHT * 0.6).unwrap();
let expected = 1.25 * SPEED_OF_LIGHT * SPEED_OF_LIGHT;

assert!((body.total_energy().unwrap() - expected).abs() < 1.0e-3);

pub fn kinetic_energy(&self) -> Option<f64>

Computes the body’s relativistic kinetic energy in joules.

pub fn momentum(&self) -> Option<f64>

Computes the body’s relativistic momentum in kilogram meters per second.

Trait Implementations

impl Clone for RelativisticBody

fn clone(&self) -> RelativisticBody

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RelativisticBody

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for RelativisticBody

fn eq(&self, other: &RelativisticBody) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
