Kepler's second law follows from angular momentum conservation, which holds for:
AAny central force at all
BOnly gravitational forces
COnly inverse-square forces
DOnly circular orbit motion
Answer & Solution
Correct answer: A. Any central force at all
A central force exerts no torque about the force centre, so angular momentum is conserved whatever the distance dependence of the force.
