Gravity in Our Galaxy

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

What two factors affect the force of gravity?

Back

Mass and Distance.

Front

How does distance affect gravitational attraction?

Back

As the distance between two objects increases, the gravitational attraction between them decreases.

Front

How does mass affect gravitational attraction?

Back

As the mass of an object increases, the gravitational attraction between it and another object increases.

Front

What is the Milky Way?

Back

The Milky Way is the name of our galaxy.

Front

What is the correct order of the first four planets from the sun?

Back

Mercury, Venus, Earth, Mars.

Front

What causes one object to orbit another in space?

Back

Gravity is what causes one object to orbit another in space.

Front

What can be found at the center of our galaxy?

Back

There is likely something we cannot see, such as a black hole, exerting a gravitational pull on the stars.

Front

What is a black hole?

Back

A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it.

Front

What is the relationship between mass and gravitational attraction?

Back

The greater the mass of an object, the stronger its gravitational attraction.
