Here is a model of the gravitational force of Mars. Objects A and B have the same mass but are different distances from Mars. Which statement explains how the gravitational force affects the two objects?
Object A and B will be affected equally by the gravitational force.
Object B will be more affected by the gravitational force because it is closer to Mars than Object A.
Object A will be more affected by the gravitational force because it is farther from Mars than Object B.
The satellite is orbiting Earth in the direction shown and is pulled toward Earth by gravity. What would happen if Earth's gravity suddenly disappeared?
The satellite would fall to Earth.
The satellite would stop moving.
The satellite would continue to orbit Earth.
The satellite would move into space in a straight line.
Observe the path of Voyager 2 satellite . Why did the route of Voyager 2 change, without firing its thrusters, as it passed Jupiter?
Gravitational force between Jupiter and Voyager 2 pulled it into a new route.
Solar winds pushed Voyager 2 into a new path.
Jupiter blocked the sun’s gravitational pull on Voyager 2.
