AP Physics Unit 3 review

• uniform circular motion:

  • constant speed
  • constant radius
  • constant acceleration (points toward center)
• circular motion acceleration equation:
• circular velocity equation:
• Newton's 2nd law with respect to circular motion:
• Curves:

  • friction points inward:
  • banked curves with no friction:
• Newton's law of gravitation:
• Kepler's laws:

  1. orbits are in elipses
  2. sweep out equal areas in equal time
