The equation to find momentum is p=mv. Change in p (or impulse)=pf-pi, or you can find the change in momentum (p) by using fnet, using the eqaution fnet=delta p/delta t or fnet(delta t)=delta p
On a graph when you are trying to find impulse, you do the area of the filled in part.
There are two types of momentum transfomations: elastic and inelastic.

Elastic(bounce off)- This is when two objects bounce off of each other. When something is perfectly elastic Eki=Ekf. The equation for elastic problems M1V1i+M2V2i=M1V1f+M2V2f.

Inelastic(stick together)- This is when two objects stick together. When this happens Eki does not equal Ekf. The equation you would use for an inelastic problem is M1V1+M2V2=(M1+M2)V3.

You can solve the same question with different methods. Using Momentum would be when you know the mass and velocity, or force and time.
