Universal Gravitation

Front

What did Newton discover about gravity?

Back

Newton discovered that gravity extends throughout the universe.

Front

What happens to gravitational force as the distance between two objects increases?

Back

Gravitational force decreases.

Front

Does the moon fall?

Back

Yes, the moon is falling around the earth due to its tangential velocity.

Front

What is Newton's Law of Gravitation?

Back

F = Gm₁m₂/r²

Front

If Earth's mass was cut in half, what would happen to your mass?

Back

Nothing, mass is not affected by gravitational force.

Front

What is the universal law of gravitation?

Back

Every point mass attracts every other point mass with a force directed along the line intersecting both points.

Front

What does 'G' represent in the gravitational formula?

Back

'G' is the gravitational constant, approximately 6.674 × 10⁻¹¹ N(m/kg)².

Front

What is the relationship between mass and gravitational force?

Back

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

Front

What is the effect of increasing mass on gravitational attraction?

Back

Increasing the mass of either object increases the gravitational attraction between them.

Front

What is the significance of the distance in the gravitational force formula?

Back

Gravitational force is inversely proportional to the square of the distance between the centers of the two masses.
