MVP — interactive sketch; a fuller lab is coming later.

Two-dimensional collision

Momentum is a vector: Σpₓ and Σp_y separately; equal-mass elastic hit on a rest target scatters at 90°.

Two-dimensional collision

2D collision: momentum in a plane. This “Two-dimensional collision” page is an MVP interactive sketch — formulas, controls, and live readouts in the browser; a fuller bench may follow.

2D collision: momentum in a plane.

How to use

  1. Adjust parameters in the left panel.
  2. Use play / pause and speed controls.
  3. Match right-side readouts to the formulas.
  4. Reset to return to the initial state.

Applications

  • Two-dimensional collision: 2D collision: momentum in a plane.
  • Classroom focus: equal-mass elastic hit on a rest target scatters at 90°.

FAQ

What does MVP mean on this page?

An interactive sketch with formulas and parameters. Polished Ready labs are the full bench experience.

What does the “Two-dimensional collision” lab practice?

Tune parameters and match readouts to the “Two-dimensional collision” relations — useful for prep and demos.

Is force always along velocity?

No. Net force aligns with acceleration; velocity can point elsewhere.

How do graphs show uniform vs accelerated motion?

Uniform: constant x–t slope. Constant a: straight v–t with slope a.
