Lecture 15: Universal gravitation
Objectives: In this lecture, students will learn to- state Kepler's Laws of planetary motion
- formulate Newton's law of universal gravitation
- relate the free-fall acceleration to mass and radius of a celestial body
- explain satellite motion in terms of circular motion under the influence of gravity
- derive Kepler's 3rd law for a circular orbit
- Powerpoint: lec15.pptx
