Per NCERT §7.2, Kepler's 2nd law (equal areas in equal times) is equivalent to conservation of which quantity?
AMechanical energy
BLinear momentum
CTotal energy
DAngular momentum
Answer & Solution
Correct answer: D. Angular momentum
NCERT §7.2: dA/dt = L/(2m) is constant since L is conserved (gravity is a central force).
