Universal Law of Gravitation

Front

What is the Law of Universal Gravitation?

Back

The Law of Universal Gravitation states that every object in the universe attracts every other object 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 happens to the gravitational force if the distance between two objects is doubled?

Back

If the distance between two objects is doubled, the gravitational force between them becomes one-fourth of the original force.

Front

If two asteroids exert a gravitational force, F, on each other and are moved three times farther apart, what happens to the gravitational force?

Back

The gravitational force becomes F/9 when the distance is tripled.

Front

Calculate the gravitational attraction between two objects with masses of 8000 kg and 1500 kg separated by 1.5 m.

Back

The gravitational attraction is 3.6 X 10^-4 N.

Front

Complete the statement: The farther away two planets are, the _______ the gravitational force between them.

Back

less.

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 of the objects, and r is the distance between their centers.

Front

What is the gravitational constant (G)?

Back

The gravitational constant (G) is approximately 6.674 × 10^-11 N(m/kg)^2.

Front

How does mass affect gravitational force?

Back

Gravitational force increases with the mass of the objects; larger masses result in a stronger gravitational attraction.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases; it is inversely proportional to the square of the distance.

Front

What is the relationship between gravitational force and the product of masses?

Back

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