use-momentum

Linear momentum, impulse, and recoil helpers for RustUse.

Foundation

use-momentum provides small f64-first helpers for linear momentum and impulse calculations.

Inputs are expected to be SI-style numeric values:

• kilograms for mass
• meters per second for velocity
• kilogram meters per second for momentum
• newton seconds for impulse
• seconds for time

The crate does not define a full unit system.

Example

use use_momentum::{MovingMass, impulse, momentum, recoil_velocity};

assert_eq!(momentum(2.0, 3.0), Some(6.0));

assert_eq!(impulse(10.0, 2.0), Some(20.0));

assert_eq!(recoil_velocity(1.0, 10.0, 5.0), Some(-2.0));
assert_eq!(MovingMass::new(2.0, 3.0).unwrap().momentum(), Some(6.0));

When to use directly

Choose use-momentum when you need small, reusable helpers for scalar momentum, impulse, and recoil.

Scope

• APIs stay f64-first and focus on one-dimensional scalar helpers.
• One-dimensional collision outcomes and restitution helpers belong in use-collision.
• Higher-dimensional vector operations should live in or compose with use-vector.
• Full rigid-body simulation and broader physics engines are out of scope.

Status

use-momentum is a pre-1.0 crate with a deliberately small API.
