How this service works
Head-on collision of two masses: velocities after impact, momentum and kinetic energy lost, elastic to perfectly inelastic.
Output
Returns the post-collision velocities of both bodies (m/s), kinetic energy before and after the collision (J), kinetic energy lost (J), total momentum (kg·m/s), centre-of-mass velocity, and the restitution coefficient used. Also includes a summary and any relevant warnings or disclaimers.
Example use cases
Elastic billiard ball collision
“I have a 0.17 kg cue ball rolling right at 3 m/s that hits a stationary 0.17 kg target ball — what are both balls' velocities after the collision, assuming it's perfectly elastic (restitution = 1)?”
Perfectly inelastic car crash energy loss
“Two cars crash head-on: car A is 1200 kg going 20 m/s to the right, car B is 900 kg going 15 m/s to the left. They crumple and stick together (restitution = 0). What's their combined velocity and how much kinetic energy is lost?”
Partial restitution Newton's cradle analysis
“A 0.5 kg steel ball hits a 0.5 kg stationary ball with a velocity of 4 m/s. With a restitution coefficient of 0.9, what are the post-collision velocities and how much energy is dissipated?”

Endpoint
GEThttps://physics-calc.x402tookit.com/collision-1d?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to compute the outcome of a one-dimensional collision between two point masses with any degree of elasticity, from perfectly elastic (restitution=1) to perfectly inelastic (restitution=0). It is ideal for physics homework, engineering simulations, game physics validation, or any scenario requiring both velocity outcomes and energy/momentum accounting in a single call.
Side effects
- Missing required parameters (m1, v1, m2, v2) returns an error
- Restitution coefficient outside 0–1 range may return an error or unexpected result
- Non-numeric values for mass or velocity cause a bad request error
- Negative mass values may be rejected or produce nonsensical output
