Describe a scenario where NASA astronauts use their understanding of gravity to navigate and perform tasks during a spacewalk.

• Astronauts ignore gravity since it does not affect them in space.

• Astronauts use heavy tools to ensure they stay grounded in the spacecraft.

• Astronauts calculate their movements and the force needed to move objects, considering the minimal gravity.

• Astronauts use magnets to simulate gravity and walk normally.

Answer explanation

Astronauts calculate their movements and the force needed to move objects, considering the minimal gravity.

Explain why astronauts experience weightlessness while orbiting Earth.

• There is no gravity in space.

• The gravitational force is too weak in space.

• The astronauts are in free fall, experiencing continuous free fall towards Earth.

• The spacecraft generates an anti-gravity field.

A comet travels through the solar system. Describe how the gravitational forces from the Sun and other planets influence its path.

• Only the Sun's gravity affects the comet.

• Only the gravity of the nearest planet affects the comet.

• The gravitational forces from the Sun and all planets influence the comet's path.

• The comet is not affected by any gravitational forces.

A satellite orbits Earth in a circular path. Explain how the gravitational force between the satellite and Earth keeps the satellite in orbit.

• The gravitational force acts as a centripetal force, pulling the satellite towards Earth.

• The gravitational force pushes the satellite away from Earth.

• The gravitational force has no effect on the satellite's orbit.

• The gravitational force only affects the satellite's speed.
