Total Momentum

Definition

Total momentum refers to the combined momentum of all objects within a system. It takes into account both mass and velocity for each individual object.

Analogy

Imagine playing billiards (pool). When you hit the cue ball, it transfers its momentum to other balls on the table. The total momentum of all the balls after the collision remains constant unless external forces act upon them.

Related terms

Impulse: Impulse is the change in momentum of an object and is equal to the force applied multiplied by the time interval over which it acts.

Conservation of momentum: This principle states that in a closed system where no external forces are present, the total momentum before an event or interaction is equal to the total momentum after.

Elastic collision: An elastic collision is a type of collision where both kinetic energy and momentum are conserved.
