Front

What happens to particles as temperatures rise?

Back

Particles move more energetically.

Front

Does a star on the other side of the universe have a gravitational pull on Earth?

Back

True.

Front

What did Einstein say gravity is caused by?

Back

The bending of space.

Front

Which phase of matter is the most abundant in the universe?

Back

It will fly out into space.

Front

Define gravitational pull.

Back

The force by which a planet or other celestial body attracts objects toward its center.

Front

What is plasma?

Back

A state of matter where gas is energized until atomic electrons are no longer associated with any particular atomic nucleus.

Front

Explain the concept of escape velocity.

Back

The minimum speed needed for an object to break free from the gravitational attraction of a celestial body.

Front

What is the relationship between temperature and particle movement?

Back

As temperature increases, particle movement becomes more energetic.
