Gravity and Motion

Question 5 • AZ-Earth and Space Science A (SC301)

Which statement describes how Earth compares to the moon?

Answer
A
Earth has more inertia than the moon.
B
The moon has more gravitational pull than Earth.
C
The moon rotates at a constant speed while Earth’s speed varies.
D
Earth and the moon will not change their motion when acted on by a force.

Explanation

Inertia is an object's resistance to changes in its motion, and it increases with mass. Earth has much more mass than the moon, so Earth has more inertia. The moon also has less gravitational pull than Earth, and both bodies can change their motion when acted on by a force.
