Question

Keplers second law regarding constancy of arial velocity of a planet is a consequence of the law of conservation of

• A. energy
• B. angular momentum
• C. linear momentum
• D. none of these

Answer 1

The correct option is B angular momentum

Kepler's second law describes the speed of a planet travelling in an elliptical orbital around the sun.It states that a line between the sun and the planet sweeps equal areas in equal times.Thus keplaer's second law regarding constancy of arial velocity of a planet is the consequence of the law of conservation of angular momentum.
