Question

A spacecraft left Earth to collect soil samples from Mars. Which statement is true about the strength of Earth’s gravity on the moving spacecraft?

a) Earth's gravity on the spacecraft remains constant throughout the journey.
b) Earth's gravity on the spacecraft weakens as it travels farther from Earth.
c) Earth's gravity on the spacecraft strengthens as it travels farther from Earth.
d) Earth's gravity on the spacecraft becomes zero once it leaves the Earth's atmosphere.

Answer 1

Earth's gravity on the spacecraft weakens as it travels farther from Earth.

Step-by-step explanation:

The statement that is true about the strength of Earth's gravity on the moving spacecraft is b) Earth's gravity on the spacecraft weakens as it travels farther from Earth. As a spacecraft travels farther from Earth, it moves into regions of space where the gravitational pull from Earth becomes weaker. This is because the force of gravity decreases with distance. Therefore, the strength of Earth's gravity on the spacecraft decreases as it travels farther from Earth.
