What is the term for the attraction between two objects that are not in contact?

Back

Gravitational force

Front

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

Back

Fg = G * (m1 * m2) / r^2, where G is the gravitational constant.

Front

What is the gravitational constant (G)?

Back

G = 6.674 × 10^-11 N(m/kg)^2

Front

If two objects have masses m1 and m2 and are separated by a distance r, how does the gravitational force change if the distance is doubled?

Back

The gravitational force is reduced to one-fourth of its original value.

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

Fg = 2 * 10^-8 N (as given in the question).

Front

How do you calculate the distance between two objects if you know their masses and the gravitational force?

Back

Rearrange the formula Fg = G * (m1 * m2) / r^2 to solve for r.

Front

What is the gravitational force between the Sun and Mars if they are 2.3*10^11 m apart?

Back

F_g = 1.6*10^21 N (as given in the question).

Front

What are the masses of the Sun and Mars?

Back

Mass of the Sun = 1.99*10^30 kg; Mass of Mars = 6.42*10^23 kg.
