Front

What is the formula to calculate gravitational force between two masses?

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 their centers.

Front

What is the value of the gravitational constant G?

Back

6.67 x 10^-11 N m^2 kg^-2

Front

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

Back

The gravitational force decreases to a fourth (1/4) of its original value.

Front

What is the area of a sphere with radius r?

Back

4pi r^2

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.

Front

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

Back

The gravitational force also triples.

Front

Define a vector field in physics.

Back

A vector field represents the influence of an object over its surrounding space, indicating the direction and magnitude of forces at different points.

Front

What is the significance of the distance in Newton's law of gravitation?

Back

The gravitational force decreases with the square of the distance between the centers of the two masses.

Front

What is the formula for calculating the force exerted by a planet on its moon?

Back

F = G * (M * m) / r^2, where M is the mass of the planet, m is the mass of the moon, and r is the distance between their centers.

Front

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

Back

The gravitational force decreases to a ninth (1/9) of its original value.
