Overview

Understanding collisions and how they are not, all the same, is a big part of physics. In this video, Dr. Shini discussed mass, momentum, and how many other things dictate how collisions can be unique.

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.
