Front

How does the gravitational force change if the mass of Earth doubles?

Back

The gravitational force on a 1 kg object on its surface would double.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its motion.

Why do planets orbit the Sun?

Back

Planets orbit the Sun due to the combination of inertia from their own motion and the gravitational force from the Sun.

What is the gravitational constant (G)?

Back

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force is directly proportional to the product of the masses of two objects.

Front

What happens to gravitational force if the distance between two objects is halved?

Back

The gravitational force increases by a factor of four, as it is inversely proportional to the square of the distance.
