AP Physics C: Laws of Gravitation - Chapter Summary

The brief videos in this chapter explore gravitation. Our expert instructors are here to help you get a handle on the laws of Newton and Kepler, along with how they predict the motion and force of moving objects. By the end of these lessons, you'll be proficient in doing the following:

  • Describe how Kepler's laws show the movement of celestial bodies
  • Apply Newton's law of gravitation
  • Explain the ways to calculate the gravitational attraction between objects
  • Work with the formula for gravitational potential energy
  • Explore work as an integral
  • Summarize elliptical orbits and their eccentricity
  • Describe speed, velocity, acceleration and centripetal force
