For many of my students, figuring which momentum equation to use (elastic, inelastic, or explosion) is half the battle. I use this before I start introducing the actual calculations. This 4 page EDITABLE worksheet gives students practice identifying which type of collision is happening and which equation is appropriate. Analysis questions ask students to dig deeper and explain the concepts using words. This can be done as a whole class, with a partner, or assigned for homework. ANSWER KEY INCLUDED.
I have uploaded this in both a PDF and .docx format so you can feel free to modify and differentiate to meet your classroom and students' needs. Enjoy!
NGSS HS-PS2-2. Use mathematical representations to support the claim that the total momentum of a system of objects is conserved when there is no net force on the system.
