Angular MomentumHardQuestion 6136

Question

A planet moves in elliptical orbit. Area swept per unit time is constant because:
  1. A
    Speed is constant
  2. B
    Angular momentum is conserved
  3. C
    Force is central
  4. D
    Both B and C
    Correct

Correct answer

Both B and C

Explanation

Kepler's 2nd law arises because gravity is a central force → no torque → angular momentum conserved → both B and C.
