Knowledge
Students know:
- Kinetic energy, how to identify other forms of energy, and have a general understanding of the conservation of energy.
- Momentum and have an understanding of the conservation of momentum.
- The appropriate units of measure.
- How to identify the system.
Skills
Students are able to:
- Collect and organize experimental data.
- Follow written and verbal instructions.
- Make measurements of velocity and mass using standard units.
- Effectively manipulate laboratory equipment.
- Interpret graphical data.
- Work safely in collaborative lab groups.
- Manipulate equations.
- Solve mathematical equations.
Understanding
Students understand that:
- Momentum and energy are always conserved.
- Kinetic energy is conserved in elastic collisions, but is not conserved in inelastic collisions.
