Gravity, Mass, and Distance

If the planets HAVE THE SAME MASS (ignore the shape in the picture), planet B has a

• Weaker gravitational attraction to the star

• Stronger gravitational attraction to the star

• Equal gravitational attraction to the star

• There is not enough data to determine a relationship

One factor responsible for the strength of gravitational attraction between a planet and the Sun is the

• Degree of tilt of the planet’s axis

• Distance between the planet and the Sun

• Planet’s period of rotation

• Amount of light given off by the Sun

As the distance from an object increases, the amount of gravitational force felt by the object

• decreases

• disappears

• increases

• stays the same

Which of the following best restates how Earth’s gravitational force on an object depends upon the distance of the object from Earth?

• The closer an object is to Earth, the less the attraction of gravity

• Earth’s gravitational force is equal to its distance from the sun

• The further an object is from Earth, the less effect Earth’s gravity has on it

• The further two objects are from one another, the greater the gravitational attraction

The force of gravity between two objects is greatest/strongest when

• masses are small and the objects are close together

• masses are small and the objects are far apart

• masses are large and the objects are close together

• masses are large and the objects are far apart
