Due to the different gravitational pulls each planet has, you would weigh differently based on what planet's surface you are on, but your mass would remain the same.

• True

• False

The pull of gravity on a planet is a direct result of the

• weight of the planets atmosphere

• rotation of planet on its axis

• magnetic field of planet

• mass and diameter of planet

Satellite B has three times more mass than Satellite A. Which satellite experiences a stronger gravitational attraction with the Earth?

• A, because it is easier to move.

• B, because it has more mass.

• Neither, since they are at the same distance.

• Neither, because they are in space.

• Cannot be determined with the given information.
