Back

Revolution: One complete trip along an orbit.

Front

What observation supports the idea that there were once glaciers on Mars?

Back

Mars has landforms that look like they were carved from its surface.

Front

What two factors affect the magnitude of the force of gravity between two objects?

Back

Mass and distance.

Front

Why do planets orbit the Sun?

Back

The Sun is the most massive object in our solar system, so it exerts the greatest gravitational pull.

Front

Which object has the greatest gravity: Sun, Jupiter, Earth, or Moon?

Back

Rotation is the spinning of an object around its own axis, while revolution is the movement of one object around another.

Front

What is a satellite?

Back

A satellite is an object that orbits a planet or another celestial body.

Front

How does mass affect gravitational force?

Back

Greater mass results in a stronger gravitational pull between objects.

Front

How does distance affect gravitational force?

Back

Greater distance results in a weaker gravitational pull between objects.
