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.
- 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.
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.
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.
