Conservation of Momentum Calculator
Calculate momentum before and after collision for two objects
Momentum Formula
Momentum (p) = mass (m) × velocity (v)
p = m × v
In a closed system, the total momentum before collision equals the total momentum after collision.

Frequently Asked Questions
What is conservation of momentum?
+
The conservation of momentum states that in a closed system with no external forces, the total momentum before an event (like a collision) is equal to the total momentum after the event. This principle is fundamental in physics and applies to all interactions between objects.
How do you calculate momentum?
+
Momentum (p) is calculated by multiplying an object’s mass (m) by its velocity (v): p = m × v. The standard unit for momentum is kilogram meters per second (kg·m/s).
Does momentum conservation apply to all collisions?
+
Momentum is conserved in all collisions when no external forces act on the system. However, kinetic energy is only conserved in elastic collisions. In inelastic collisions, some kinetic energy is converted to other forms of energy, but momentum is still conserved.
