Lesson 3: Universal Law of Gravitation

Question 1 • Crowley Credit Recovery Physics A

The acceleration due to gravity on the moon is 1.6 m/s2, about a sixth that of Earth’s. Which accurately describes the weight of an object on the moon?

Answer
A
An object on the moon is 1.6 times lighter than on Earth.
B
An object on the moon is 1.6 times heavier than on Earth.
C
An object on the moon is six times lighter than on Earth.
D
An object on the moon is six times heavier than on Earth.

Explanation

Weight depends on gravitational acceleration: weight = mass × gravity. The Moon’s gravity is about one-sixth of Earth’s, so the same object weighs one-sixth as much there. Thus, it is six times lighter on the Moon, matching choice C.
