CAIE IGCSE Physics 6.1.2.10 An Object in an Elliptical Orbit Questions

Learn how gravitational and kinetic energy exchange as an orbiting object moves closer to or further from the Sun.

Exam points

identify greatest speed closest to the Sun and slowest speed furthest from it
explain approach to the Sun as gravitational potential energy decreases while kinetic energy increases
reverse the energy transfer as the object moves away while total energy remains conserved

[Maximum number: 2]

Fig. 10.1 shows the orbit of an object around the Sun. At point A, the object is closest to the Sun. At point B, the object is furthest away from the Sun.
