| 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) New ton's second law of motion
C) Ohm's law
D) Newton's law of gravitation
Correct Answer: A
Solution :
The point of Kepler's Und law is that, although the orbit is symmetric, the motion is not. A planet speeds up as it approaches the sun, gets its greatest velocity when passing closest, then slowest down again and the earth moves fastest at perihelion and slowest at aphelion.
