Elastic Collision Calculator
Solve elastic: p and KE both conserved step by step — free elastic collision calculator with worked examples, real-world defaults and instant answers.
Perfectly elastic 1-D collision — both final velocities with energy check.
About Elastic Collision Calculator
The Elastic Collision Calculator solves elastic: p and KE both conserved for you with the full working shown — every substitution, every unit, every step, exactly the way a good teacher writes it on the board. Special cases worth memorising: equal masses simply SWAP velocities (Newton's cradle); a light ball off a heavy wall bounces back at nearly the same speed.
How to use Elastic Collision Calculator
- 1Enter your known values in the input fields (sensible real-world defaults are pre-filled).
- 2The tool substitutes them into elastic: p and KE both conserved and recomputes live.
- 3Read the answer in the result box, then expand the step-by-step solution to see the full working.
- 4Copy the method into your notebook, or change inputs to explore how the result behaves.

Frequently asked questions
What formula does the Elastic Collision Calculator use?+
It uses elastic: p and KE both conserved. The steps section shows the formula with your actual numbers substituted, so you can follow (and verify) every stage of the calculation rather than trusting a black box.
What should I keep in mind when using this calculator?+
Special cases worth memorising: equal masses simply SWAP velocities (Newton's cradle); a light ball off a heavy wall bounces back at nearly the same speed. Use negative velocity for leftward motion.
Is the Elastic Collision Calculator free to use?+
Completely free, with no sign-up or limits. All computation happens client-side in your browser, so it is fast, private, and works even on slow connections once the page has loaded.
Can I use this for homework, teaching or exam prep?+
That is exactly what it is built for. The step-by-step working mirrors how solutions are presented in class, so you can check homework, build worked examples for teaching, or practise method recall before exams.
