Inelastic Collision Calculator
Solve v′ = (m₁u₁ + m₂u₂) / (m₁ + m₂) step by step — free inelastic collision calculator with worked examples, real-world defaults and instant answers.
Perfectly inelastic collision — bodies stick together.
About Inelastic Collision Calculator
The Inelastic Collision Calculator solves v′ = (m₁u₁ + m₂u₂) / (m₁ + m₂) for you with the full working shown — every substitution, every unit, every step, exactly the way a good teacher writes it on the board. Momentum survives every collision; kinetic energy does not.
How to use Inelastic Collision Calculator
- 1Enter your known values in the input fields (sensible real-world defaults are pre-filled).
- 2The tool substitutes them into v′ = (m₁u₁ + m₂u₂) / (m₁ + m₂) 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 Inelastic Collision Calculator use?+
It uses v′ = (m₁u₁ + m₂u₂) / (m₁ + m₂). 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?+
Momentum survives every collision; kinetic energy does not. Here a 1200 kg car at 15 m/s rear-ends a stationary 1500 kg SUV: the pair rolls on at 6.7 m/s and ~55 kJ becomes crumpled metal and heat.
Is the Inelastic 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.
