Conservation of Momentum Calculator (Final Velocity)

Enter the mass, initial velocity, and final velocity of object 1, and the mass and initial velocity of object two, 2 calculate the final velocity of object 2. This is valid for a perfectly inelastic collision of two objects only.

Conservation of Momentum Formula

The following formula is used in the conservation of momentum of two objects undergoing and inelastic collision.

M1*V1=M2*V2

  • Where m1 is the mass of object 1
  • V1 is the change in velocity of object 1
  • M2 is the mass of object 2
  • and V2 is the change in velocity of object 2

In other words v1 and v2 are the final velocities minus the initial velocity. This equation is the law of the conservation of momentum. In this case, since v contains both the initial and final velocities, if the other variables are known than the equation can be used to solve for the missing variable.

FAQ

What is conservation of momentum?

Conservation of momentum is a law of physics that says that momentum must be conserved in a close system. In other words momentum cannot changed in a closed system unless acted on by an outside force.

How does momentum change?

Momentum can change through one of two ways. Through a change in velocity or a change in mass. Most often, since the mass of objects rarely change, the velocity is what is changing.
