Big Ideas
- Momentum is a fundamental property of objects in motion, and it is conserved in a system when there is no net external force.
- Mathematical representations enable scientists to support and explain the conservation of momentum in physical systems.
Essential Questions
- What does it mean for momentum to be conserved in a system of objects?
- How can mathematical representations be used to show that momentum is conserved?
- Under what conditions is the total momentum of a system unchanged?
- How does the presence or absence of a net force affect the momentum of a system?
- Why is it important to support scientific claims about physical phenomena with mathematical evidence?
