Front

What happens to the moon's orbit if there is no gravitational force between Earth and the moon?

Back

The moon would continue to travel in a straight line at a constant speed, leaving its orbit.

Front

How does the moon's increasing distance from Earth affect its orbital motion?

Back

The moon would orbit slower and have a greater orbital path.

Front

What is the name of the doughnut-shaped region just past Neptune where icy objects have stable orbits?

Back

The Kuiper Belt.

Front

How are asteroids, comets, and meteors related?

Back

Meteors are small fragments that break from the icy bodies of comets or the rocky bodies of asteroids orbiting the sun and enter Earth’s atmosphere.

Front

Which planet has the shortest orbital period?

Back

Mercury.

Front

What is inertia in the context of celestial bodies?

Back

Inertia is the tendency of an object to resist changes in its state of motion, meaning a body in motion will stay in motion unless acted upon by an external force.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses, such as the Earth and the moon, which keeps the moon in orbit.

Front

What is the difference between asteroids and comets?

Back

Asteroids are rocky bodies that orbit the sun, while comets are icy bodies that release gas or dust when they come close to the sun.

Front

What is the significance of the Kuiper Belt?

Back

The Kuiper Belt is significant because it contains many small icy bodies and is the source of short-period comets.
