Law of Universal Gravitation

Front

What is the Law of Universal Gravitation?

Back

The Law of Universal Gravitation states that every point mass attracts every other point mass in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Front

What two factors affect the gravitational force between two objects?

Back

Mass and distance.

Front

How does the gravitational force change with distance?

Back

The gravitational force decreases as the distance between two objects increases.

Front

What happens to the gravitational force if the masses of two objects are doubled?

Back

The gravitational force becomes four times greater.

Front

If two objects have masses of 10 kg and 20 kg and are 2 meters apart, what is the gravitational force between them?

Back

Using the formula F = G(m1*m2)/r^2, where G is the gravitational constant, the force can be calculated.

Front

What is the gravitational force between two objects that are 1 meter apart with masses of 5 kg and 10 kg?

Back

F = G(5*10)/1^2 = 50G, where G is the gravitational constant.

Front

What is the relationship between gravitational force and mass?

Back

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

Front

What is the relationship between gravitational force and distance?

Back

Gravitational force is inversely proportional to the square of the distance between the objects.

Front

If the distance between two objects is halved, how does the gravitational force change?

Back

The gravitational force increases by a factor of four.

Front

What is the formula for calculating gravitational force?

Back

F = G(m1*m2)/r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between the centers.
