Front

What is the nature of the gravitational force between two massive spheres?

Back

The gravitational force is always an attraction.

Front

What does the gravitational force depend on?

Back

The gravitational force depends on how massive the objects are.

Front

How does distance affect gravitational force?

Back

The gravitational force depends inversely on the square of the distance between the two masses.

Front

What is the universal law of gravitation?

Back

The universal law of gravitation states that every point mass attracts every other point mass 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

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.

Front

What is gravitational constant (G)?

Back

The gravitational constant (G) is a proportionality factor used in the equation of gravitational force, approximately equal to 6.674 × 10^-11 N(m/kg)^2.

Front

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

Back

If the distance is doubled, the gravitational force becomes one-fourth as strong.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force increases with an increase in mass.

Front

Can gravitational force act at a distance?

Back

Yes, gravitational force can act at a distance without direct contact between the masses.

Front

What is weight in terms of gravitational force?

Back

Weight is the gravitational force acting on an object, calculated as W = m * g, where g is the acceleration due to gravity.
