How to use the Conservation of Momentum Calculator
- Fill in the values you know. Fields already contain typical example values that you can overwrite.
- Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
- Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
- A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.
If a value is missing or does not make sense, the field shows a short message explaining what to fix.
Formulas used
This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:
mass_object1 × (v2_object1 - v1_object1) = -mass_object2 × (v2_object2 - v1_object2)
KEloss =(KE1-KE2)/KE1
KE1 = 0.5×mass_object1 × (v1_object1)^2 + 0.5×mass_object2 × (v1_object2)^2
KE2 = 0.5×mass_object1 × (v2_object1)^2 + 0.5×mass_object2 × (v2_object2)^2
v2_object1_elastic = ((mass_object1 - mass_object2)/(mass_object1 + mass_object2)) × v1_object1 + ((2 × mass_object2)/(mass_object1 + mass_object2)) × v1_object2
v2_object2_elastic = ((2 × mass_object1)/(mass_object1 + mass_object2)) × v1_object1 + ((mass_object2 - mass_object1)/(mass_object1 + mass_object2)) × v1_object2
The calculator uses 6 further relationships to link its other values.

Frequently asked questions
What is the conservation of momentum?
The conservation of momentum is a fundamental principle in physics stating that the total momentum of a closed system remains constant over time, provided no external forces are acting on it. This principle is crucial in analyzing collisions and interactions between objects.
How does the Conservation of Momentum Calculator work?
The Conservation of Momentum Calculator facilitates the calculation of momentum before and after an event, usually a collision. It uses the masses and velocities of involved objects to ensure that total momentum is conserved through mathematical equations.
When should I use a Conservation of Momentum Calculator?
You should use this calculator when analyzing collisions or interactions in physics problems, especially in mechanics. It’s particularly useful for both elastic and inelastic collisions where momentum conservation applies.
Is the calculator suitable for both elastic and inelastic collisions?
Yes, the calculator can accommodate both elastic and inelastic collisions. In elastic collisions, both momentum and kinetic energy are conserved, while in inelastic collisions, only momentum is conserved. The calculator helps you determine outcomes for both scenarios.
Can I use the calculator for more than two objects?
Yes, many advanced calculators can handle multiple objects. As long as you input the correct masses and velocities, the Conservation of Momentum Calculator will compute the total momentum and provide results for all objects involved in the interaction.
