1. The Earth does not move along its orbit at a constant rate. |
2. The Earth moves fastest at perihelion and slowest at aphelion. |
A) Kepler's second law
B) Newton's second law of motion
C) Ohm's law
D) Newton's law of gravitation
Correct Answer: A
Solution :
Kepler's second law of planetary motion describes the speed of a planet travelling in an elliptical orbit around the sun. It states that a line between the sun and the planet sweeps equal areas in equal times. Thus, the speed of the planet increases as it nears the sun and decreases as it recedes from the sun.You need to login to perform this action.
