Struct MovingMass 

pub struct MovingMass {
    pub mass: f64,
    pub velocity: f64,
}

A moving mass with scalar velocity.

Fields

mass: f64

velocity: f64

Implementations

impl MovingMass

pub fn new(mass: f64, velocity: f64) -> Option<MovingMass>

Creates a moving mass when mass is non-negative and both values are finite.

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

Computes linear momentum using p = m * v.

Examples

use use_momentum::MovingMass;

let moving_mass = MovingMass::new(2.0, 3.0).unwrap();

assert_eq!(moving_mass.momentum(), Some(6.0));

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

Computes kinetic energy using 0.5 * m * v^2.

Trait Implementations

impl Clone for MovingMass

fn clone(&self) -> MovingMass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MovingMass

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

Formats the value using the given formatter.

impl PartialEq for MovingMass

fn eq(&self, other: &MovingMass) -> 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.
