  • video D1: Momentum Basics
    • This video shows how momentum conservation follows from Newton's laws of motion.
  • video D2: Types of Collisions
    • This video details the different types of collisions between two objects.
  • video D3: Types of Collisions (part 2).
  • video D4: Collisions in 2 Dimensions
    • This video details the physics that occurs when the collision is not "head-on" but rather "off-center" so that the two objects travel off of their original straight-line paths.

For more complicated problems involving conservation of potential/kinetic energies, watch this (although it won't come up during recitation).

[3] Recitation Prep⚓︎

I recommend reviewing the following concepts, they will probably come up in recitation:

• 1D...
  • One object bouncing against something.
  • Two objects bouncing against each other (elastic/inelastic).
• 2D...
  • Elastic/inelastic collisions between two objects travelling at different speeds/directions (e.g. one North and one East, or "glancing blow" where one object hits another at an angle).
