Question

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?

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.

Answer 1

C)the astronauts weight decreases because the moons gravitational acceleration is less than earth's

Answer 2

(a) The acceleration due to gravity on the moon is about one-sixth of that on the earth. (b) In order to the force of gravitation between two bodies to become noticeable and cause motion, one of the bodies must have an extremely large mass.
