Law of Gravitation

Front

What is the Law of Gravitation?

Back

The Law of 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 is the formula for the gravitational force between two masses?

Back

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

Front

What is the value of the Universal Gravitational Constant (G)?

Back

G = 6.673 x 10^-11 Nm^2/kg^2.

Front

How does the gravitational force change if the distance between two masses is doubled?

Back

If the distance (r) is doubled, the gravitational force becomes 1/4 of its original value, since F is inversely proportional to r^2.

Front

What happens to the gravitational force if one of the masses is doubled?

Back

If one of the masses (m1 or m2) is doubled, the gravitational force also doubles.

Front

Who formulated the Law of Universal Gravitation?

Back

Sir Isaac Newton.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force is directly proportional to the product of the masses involved.

Front

What is the effect of increasing both masses by a factor of 2 on the gravitational force?

Back

The gravitational force increases by a factor of 4, since F is proportional to m1 * m2.

Front

What is the significance of the gravitational force in the universe?

Back

Gravitational force is responsible for the attraction between celestial bodies, keeping planets in orbit around stars and moons around planets.

Front

What is an example of gravitational force in everyday life?

Back

The weight of an object on Earth is the gravitational force acting on it due to Earth's mass.
