Energy Changes Within and between Circular & Elliptical Orbits // HSC Physics

This video discusses the variation in kinetic, gravitational potential energy and total energy for objects in orbit. We will also discuss how energy forms change as objects move between orbits of different radius.

⌚Timestamp
00:00 What forms of energy are present in an orbit?
00:52 Energy changes in a circular orbit
03:07 Energy changes in an elliptical orbit
09:00 Energy change between orbits

📚Syllabus
• Derive quantitatively and apply the concepts of gravitational force and gravitational potential energy in radial gravitational fields to a variety of situations, including but not limited to:  
– the concept of escape velocity 𝑣_esc=√(2𝐺𝑀/𝑟)
– total potential energy of a planet or satellite in its orbit U=−𝐺𝑀𝑚/𝑟
– total energy of a planet or satellite in its orbit U+K=−𝐺𝑀𝑚/2𝑟
– energy changes that occur when satellites move between orbits
– Kepler’s Laws of Planetary Motion

How does energy change throughout a circular orbit? How does energy change throughout an elliptical orbit? Law of conservation of energy in orbits. How does energy change as an object move between orbits?
