Gravity and the Universe

Front

What are the two factors affecting the magnitude of the force of gravity between two objects?

Back

Mass and distance.

Front

What does inertia cause a moving object to do?

Back

Keep moving.

Front

What stage of solar system formation involves gravity causing a rotating cloud of gas, ice, and dust?

Back

The initial stage of solar system formation.

Front

What is the basic shape of every planet's orbit?

Back

Elliptical.

Front

What is gravity?

Back

A force that attracts two bodies towards each other.

Front

How does mass affect gravity?

Back

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

Front

How does distance affect gravity?

Back

The greater the distance between two objects, the weaker the gravitational force between them.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the role of gravity in the formation of stars?

Back

Gravity pulls together gas and dust to form stars.

Front

What is a black hole?

Back

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