What is Universal Gravitation?

Back

Universal Gravitation is a fundamental force of nature that describes the attraction between two masses. It 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 is the formula for gravitational force?

Back

The formula for gravitational force (F) is given by F = G * (m1 * m2) / r^2, where G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between their centers.

Front

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

Back

If the distance between two objects is doubled, the gravitational force becomes 4 times smaller.

Front

If two objects exert a gravitational force of 36 N, what is the force if the distance is doubled?

Back

The gravitational force would be 9 N if the distance is doubled.

Front

What is the gravitational force between two objects with masses 4500 kg and 8700 kg separated by a distance of 361.34 m?

Back

The gravitational force is 2.0 x 10^-8 N.

Front

True or False: Gravity attracts all objects towards one another.

Back

True.

Front

What is the effect of increasing the distance between two masses on the gravitational force?

Back

Increasing the distance decreases the gravitational force, following the inverse square law.

Front

What is the gravitational constant (G)?

Back

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

Front

If two asteroids are three times as far apart, how does the gravitational force change?

Back

The gravitational force becomes 1/9 of the original force.

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.
