a force that is not balanced by other forces. ... If a system is not isolated, then the total system momentum is not conserved. To understand this concept, we will return to ... If the collision being analyzed involved objects with even greater speeds, the percent loss of total system momentum would be considerably less.

The study of collision is not suited for force analysis, using laws of motion. ... For this reason, we shall neglect external forces unless stated otherwise. As such, linear momentum of the system of colliding objects is conserved. This means that linear momentum of the system before and after the collision is same.

Note: This is a vector equation! (I.e., it is true for all components of the vectors.); This is very useful whenever the forces in a system are complex such as in collisions and explosions. Often, the forces involved are NOT conservative, yet momentum is still conserved! ... 2; Collisions; In a collision between two objects,

So we cover not only car accidents but also balls colliding on a biliard table, etc…. ... As aforementioned, an elastic collision in an isolated system is a collision in which kinetic energy (as well as momentum) is conserved. Elastic collisions occur when forces between the colliding bodies are conservative.

If velocity is understood, it is explained that momentum is equal to the mass of an object times its velocity. Speed can be used if the concept of velocity and speed being different is fully grasped. Next it is explained that in a system, neglecting outside forces, momentum is conserved in an elastic collision.

Assuming no other forces act on the balls and the collision is linear, then the momentum is conserved. Momentum conservation occurs whether or not the collision is elastic. m v = p ... Can it?Well, it sounds like the authors of your text are neglecting their target audience (or it was poorly chosen for your course).
