How does the Inelastic Collision Calculator work?

Enter masses and velocities of colliding objects Then: The calculator conserves momentum: m₁v₁ + m₂v₂ = (m₁ + m₂)v_final Then: Results show final velocity and energy loss.

Can you give an example of how to use the Inelastic Collision Calculator?

Example: Input m₁ = 1 kg, v₁ = 10 m/s, m₂ = 1 kg, v₂ = 0 m/s (perfectly inelastic) gives a result of v_final = 5 m/s, ΔKE = 25 J lost (Momentum conserved, energy not).

Is the Inelastic Collision Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.

How accurate is the Inelastic Collision Calculator?

Our Inelastic Collision Calculator uses verified mathematical formulas and is accurate to multiple decimal places. Results are calculated in real-time using the same methods used by professionals.
