What is gravitational force?

Back

Gravitational force is the attraction between two objects with mass. It pulls objects toward each other.

Front

How does distance affect gravitational force?

Back

The farther away two objects are, the less gravitational force acts between them.

Front

What is a contact force?

Back

Contact forces are forces that require two objects to be in contact with each other, such as friction and tension.

Front

What is a non-contact force?

Back

Non-contact forces are forces that act at a distance, such as gravitational, magnetic, and electrical forces.

Front

What keeps planets in orbit around the sun?

Back

Gravitational force keeps planets in motion around the sun.

Front

Why is gravity on the moon less than on Earth?

Back

Gravity on the moon is less than on Earth because the moon has less mass.

Front

What is the relationship between mass and gravitational force?

Back

The greater the mass of an object, the stronger the gravitational force it exerts.

Front

What is air resistance?

Back

Air resistance is a type of frictional force that opposes the motion of an object through the air.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is an example of a magnetic force?

Back

An example of a magnetic force is the attraction or repulsion between magnets.
