This video in on the concept of gravitational potential energy and work done within a gravitational field. This video contains an explanation for why gravitational potential energy is negative. ⌚Timestamp 00:00 Why U = mgh is not used in space 02:42 New equation for gravitational potential energy 04:59 How potential energy varies with distance r 07:17 Work done in a gravitational field 09:31 Calculation example 📚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
