Momentum is an objects tendency to stay in motion and the product of the velocity and the mass. Impulse is the change in momentum and is also the product of the Average force and the time. The impulse can also be calculated by finding the area underneath a force vs time graph.

Collisions
Elastic Collisions
Sometimes called hard collisions
When no kinetic energy is lost and no deformation occurs
Inelastic Collisions
When deformation occurs and kinetic energy is lost
Perfectly Inelastic Collisions
When objects stick together and become one object
Deformation occurs
Kinetic energy is lost

Momentum Bar Charts
By Myself
Momentum bar charts are used to show the change in momentum before and after a collision. The middle section represents the momentum lost from the system and it is called the impulse or J.
Conservation of Momentum
https://www.youtube.com/watch?v=2E9fY8H6O1g
Momentum will stay conserved if in an isolated system which is when there are no external forced acting upon the system causing an impulse.
Impulse
Impulse (J) is the change in momentum. It can be calculated by average force*time or by finding the area under a force vs time graph.

Momentum Derivations
Momentum is derived from the mass and the velocity which is from kinematics. The impulse is from the average force and the time which is also from previous units. It is related to the previous units and builds off of all of them.
