Explain why an astronaut weighs less on the Moon than on Earth.

• The Moon has less mass than Earth, resulting in weaker gravitational pull.

• The astronaut's mass decreases on the Moon.

• The Moon has a stronger gravitational pull than Earth.

• The astronaut's weight remains the same on the Moon.

• The weight increases because Mars has a stronger gravitational pull.

• The weight decreases because Mars has a weaker gravitational pull.

• The weight remains the same because mass does not change.

• The weight becomes zero because Mars has no gravity.
