Front

Define gravity in the context of celestial bodies.

Back

Gravity is the force that attracts two bodies towards each other, proportional to their masses and inversely proportional to the square of the distance between them.

Front

What is the formula for calculating 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 the centers of the two masses.
