Chapter 9
Definition of linearmomentum of a particle
The linear momentum of a particle or an object that can be modeled as a particle of mass m moving with a velocity v is defined to be the product of the mass and velocity:

Using the definition of momentum
Impulse and Momentum
The impulse of the force F acting on a particle equals the change in the momentum of the particle.

Collisions in One Dimension
elastic collision between two objects is one in which the total kinetic energy (as well as total momentum) of the system is the same before and after the collision.
An inelastic collision is one in which the total kinetic energy of the system is
not the same before and after the collision (even though the momentum of the
system is conserved).
momentum of the system is conserved in all collisions, but kinetic energy of the system is conserved only inelastic collisions.
