Lesson 4: Momentum & Collisions
Duration of Days: 3
Lesson Objective
Students will be able to (I can) describe various collisions, including elastic and inelastic as well as describe impulse during a collision.
What is a collision?
What happens during a collision?
Are forces at work during a collision?
Is energy lost during a collision?
Momentum
Collision
Elastic collision
Inelastic collision
Impulse
GS1: Questioning
Students can develop and use relevant scientific questions to investigate phenomena, test a hypothesis, conduct an experiment or solve a problem.
GS3: Modeling
Students can construct and use models to represent and analyze phenomena and systems.
Mathematic skills to relevant formulas. Algebraic thinking.
The purpose of this lesson is to solidify students understanding of what a collision is and how we classify collisions. This is important for understanding changes in momentum and energy in subsequent lessons.
DOK: 2-3
Real world examples- such as car collisions, or objects bouncing off of each other. Objects speeding up or slowing down.
Students tend to mix up the difference between elastic and inelastic collisions.
Both collisions can be connected or present at the same time.

Students will answer questions about specific collisions either shown in videos or described. They will try to describe the impulse given force versus time graphs.
Laptop
Programs such as gizmo or virtual ways to observe and conduct collisions.
Collision Lab- different sports balls being dropped or colliding with floor, walls or themselves to observe collisions and forces.
