- 7.1: Introduction
- Linear momentum is the product of the mass and velocity of an object, it is conserved in elastic and inelastic collisions.
- 7.2: Conservation of Momentum
- Net external forces (that are nonzero) change the total momentum of the system, while internal forces do not.
- 7.3: Collisions
- In an inelastic collision the total kinetic energy after the collision is not equal to the total kinetic energy before the collision.
- 7.4: Rocket Propulsion
- In rocket propulsion, matter is forcefully ejected from a system, producing an equal and opposite reaction on what remains.
- 7.5: Center of Mass
- The position of COM is mass weighted average of the positions of particles.
