The gravitational acceleration on the moon is about one-sixth the size of the gravitational acceleration on Earth. According to Newton’s second law of motion, what happens to an astronaut who goes to the moon?
Answer
A
The astronaut’s weight decreases because the moon’s gravitational acceleration is greater than Earth’s.
B
The astronaut’s weight increases because the moon’s gravitational acceleration is greater than Earth’s.
C
The astronaut’s weight decreases because the moon’s gravitational acceleration is less than Earth’s.
D
The astronaut’s weight increases because the moon’s gravitational acceleration is less than Earth’s.
