Solar System Scale and Gravity test review

Front

What is gravity?

Back

Gravity is a force that causes objects to pull towards one another.

Front

How do the sizes of the inner planets compare to the outer planets?

Back

The inner planets are smaller than the outer planets.

Front

What is the relationship between the distances of the orbits of the inner and outer planets?

Back

The distances between the orbits of the outer planets are much larger than those of the inner planets.

Front

What two factors determine the strength of gravity?

Back

The strength of gravity is determined by mass and distance.

Front

When is the gravitational force between two objects the least?

Back

The gravitational force is least when the masses of both objects are small and they are far apart.

Front

What are the four inner planets of the solar system?

Back

The four inner planets are Mercury, Venus, Earth, and Mars.

Front

What are the four outer planets of the solar system?

Back

The four outer planets are Jupiter, Saturn, Uranus, and Neptune.

Front

How does mass affect gravitational force?

Back

Greater mass results in a stronger gravitational force.

Front

How does distance affect gravitational force?

Back

Greater distance results in a weaker gravitational force.

Front

What is the significance of the sun's gravity in the solar system?

Back

The sun's gravity keeps the planets in orbit around it.
