Ch6: Gravitational Fields

6.1 – Gravitational Fields

6.2 – Orbits & Keplers Laws

Models of the Solar System Geocentric The theory which stated that the Earth was the center of the solar system, believed to be an accurate description of the solar system until the17th century. Heliocentric The true model of the solar system in which the Sun is the center around which the planets orbit.

6.3 - Gravitational Potential Energy

Expression for gravitational potential energy of a system of any two masses a finite distance apart For example: it gives the gravitational potential energy between two masses, such as a Earth-satellite system
